Server Errors, Help me!
Archive: 47 posts
| Is anybody else getting a slew of 'Server Not Found' or 'Internal Server Error' messages? Every other link I click on gives me a server error, and it is right frustrating. Anybody else having the problem, or know of a way to make it stop? Cheers, Comph | 2010-03-14 17:08:00 Author: comphermc  Posts: 5338 |
| D: Not this again. Don't tell me we have to get rid of ArrowChat! I've only seen the internal server error once.... so far D: | 2010-03-14 17:15:00 Author: Doopz  Posts: 5592 |
| I know, i started getting surver errors too. I really hope it doesnt have to do with arrow chat. | 2010-03-14 17:17:00 Author: orang3dragon612  Posts: 243 |
| No, no. Don't worry guys... this started a few days ago. It had been getting worse and worse... to the point of cutting out every 5-10 minutes for about half a minute. | 2010-03-14 17:19:00 Author: comphermc Posts: 5338 |
| Oh, well I just got it the one time today (when ArrowChat came) | 2010-03-14 17:24:00 Author: Doopz Posts: 5592 |
| I've been getting server errors in the last few days too but not as frequently as you by the sound of it. Mine are probably happening a couple of times an evening/day. My browser is Google Chrome. | 2010-03-14 18:00:00 Author: shropshirelass  Posts: 1455 |
| I don't even know what arrow chat is. I got an internal error (I think the number was about 550…something like that), but I hit refresh and it worked out. -shrug- | 2010-03-14 18:22:00 Author: Ragfell  Posts: 729 |
| My life is plagued by these: http://img387.imageshack.us/img387/8220/internal.jpg http://img291.imageshack.us/img291/8476/servernotfound.jpg Only here and MNRCentral. Everywhere else is fine.  | 2010-03-14 20:13:00 Author: comphermc Posts: 5338 |
| Could be that CC is doing some things in the background getting chat configured properly and rippling the server. | 2010-03-14 20:15:00 Author: jwwphotos  Posts: 11383 |
| Noop. Been doing that for a few days now. I've been chatting with him when it happens and he says that is able to use it at the exact same time with no issues. | 2010-03-14 20:20:00 Author: comphermc Posts: 5338 |
| I've been getting a lot of these today on LBPC, I don't think I've gotten them before today though, but the site has been a bit slow lately. Edit: Also I've gotten one while posting this reply, lol. | 2010-03-14 20:21:00 Author: Gilgamesh  Posts: 2536 |
| i have had them also today. | 2010-03-14 20:50:00 Author: Smelling-Cowboy  Posts: 668 |
| I've been having a few right now too... gah this is just great | 2010-03-14 20:53:00 Author: RockSauron  Posts: 10882 |
| I have had two in the past 5 minutes when replying to posts. Only problem is then that the new post don't seem to be showing as the latest post in a thread, yet when you go to look at the thread, the latest post is there... | 2010-03-14 21:00:00 Author: mnimmo1986  Posts: 552 |
| I just had this: http://img695.imageshack.us/img695/4581/screenshot31410358.png I ping'd the site to see if it was due to a packet loss causing an incomplete query or just something else on the way to the site, but it seems to be fine. Seems like a hiccup and not much more. | 2010-03-14 21:01:00 Author: Hibbsi  Posts: 203 |
| Is anybody else getting a slew of 'Server Not Found' or 'Internal Server Error' messages? Yep, but only since arrowchat went live. Hardly surprising really. The only way such a program can know whether you have a new incoming message or not, is to frequently poll the server - meaning that the server load has just increased by probably 100 times, and the 500 errors are often the result of an overloaded server. | 2010-03-14 21:28:00 Author: Aya042  Posts: 2870 |
| http://img387.imageshack.us/img387/8220/internal.jpg Hmm... mines more like this: http://i1015.photobucket.com/albums/af273/Doopz479/Publication.gif?t=1268599059 Yep, that's right the LBPCentral font.  | 2010-03-14 21:40:00 Author: Doopz Posts: 5592 |
| The only way such a program can know whether you have a new incoming message or not, is to frequently poll the server. Okay. I was wrong. It's using a technique called long polling (http://en.wikipedia.org/wiki/Push_technology#Long_polling) (source (http://www.arrowchat.com/forum/viewtopic.php?f=8&t=169)) so the bottleneck will be on open sockets. Note that every tab opened by every user is holding open a connection to the server, so you might need to increase apache's MaxClients directive. I have five tabs open to LBP Central, and... C:>netstat -n Active Connections Proto Local Address Foreign Address State TCP 192.168.2.25:53298 208.86.184.190:80 ESTABLISHED TCP 192.168.2.25:53305 208.86.184.190:80 ESTABLISHED TCP 192.168.2.25:53320 208.86.184.190:80 ESTABLISHED TCP 192.168.2.25:53350 208.86.184.190:80 ESTABLISHED TCP 192.168.2.25:53364 208.86.184.190:80 ESTABLISHED TCP 192.168.2.25:53398 208.86.184.190:80 CLOSE_WAIT TCP 192.168.2.25:53412 208.86.184.190:80 ESTABLISHED TCP 192.168.2.25:53413 208.86.184.190:80 CLOSE_WAIT ...there are six active connections to the webserver. | 2010-03-14 22:20:00 Author: Aya042 Posts: 2870 |
| Well, this is quite interesting. It seems that Arrowchat is no less taxing than cometchat. As for your observation, Mnimmo, that is just a byproduct of the errors. When you make a reply, it temporarily resides just below the post you are replying to. When the page refreshes, as it's supposed to, it bumps it to the bottom. So, in your case, as in the case of myself a few times lately, the page didn't refresh, so your post didn't seem to move. When you return to the thread, though, it completely refreshes, and it is shown correctly. :/ Edit: Haha, not sure what Aya said just there, but I'm gonna stand behind what he said. Yeah! What he said! Edit2: I see your edits. So, is multiple tabbing killing the server load, then? Excuse my dense-ness in the matter. | 2010-03-14 22:22:00 Author: comphermc Posts: 5338 |
| So, is multiple tabbing killing the server load, then? Not necessarily 'load' in the traditional sense, although that fourm post I just linked to on arrowchat's website seems to suggest that there are still some issues to work out. Basically the webserver has a configuration parameter which limits the total number of connections, because each one uses up memory. If each tab is holding open one connection for an extended period of time, then all of the forum users are effectively fighting over the few remaining free connections. The result will be slow-loading pages, pages which don't load at all, and potenially our good old friend, the 500 Internal Server Error, although that's more likely indicative of a problem elsewhere, such as database contention. | 2010-03-14 22:41:00 Author: Aya042 Posts: 2870 |
CC just made a few tweaks to the chat... we'll see if it helps any.  | 2010-03-14 22:47:00 Author: comphermc Posts: 5338 |
| This was definitely anticipated, and we are currently tweaking settings to ensure optimal performance. I can't guarantee these will completely go away any time soon, but we are definitely working towards that end as much as possible. | 2010-03-14 22:49:00 Author: ConfusedCartman  Posts: 3729 |
| I can't guarantee these will completely go away any time soon, but we are definitely working towards that end as much as possible. In the interim, is there a way to completely disable the chat on a per-user basis? I can disable JavaScript from running completely, but then certain other aspects of the site refuse to work. | 2010-03-14 23:17:00 Author: Aya042 Posts: 2870 |
| Just heard from Morgana. She can't get the site to load at all. She's getting time-outs. | 2010-03-14 23:32:00 Author: comphermc Posts: 5338 |
| In the interim, is there a way to completely disable the chat on a per-user basis? Actually. Doesn't matter. Seems that as long as you keep the chat thing hidden, the connections die off pretty fast. Just heard from Morgana. She can't get the site to load at all. She's getting time-outs. I was getting that earlier, as if the webserver was down for a while. Is she using an unusual browser? | 2010-03-14 23:40:00 Author: Aya042 Posts: 2870 |
| Actually. Doesn't matter. Seems that as long as you keep the chat thing hidden, the connections die off pretty fast. The option has been added regardless. Just head to the "Forum Settings" section of your "Settings" page, and at the bottom you'll see an option to enable/disable Arrowchat. | 2010-03-15 00:08:00 Author: ConfusedCartman Posts: 3729 |
| I clicked on sevhen's profile and there were two different site banners in a line. lol. | 2010-03-15 00:11:00 Author: Incinerator22  Posts: 3251 |
| Yeah, I was getting black glitchy backgrounds there for a while. They're gone now, so maybe CC was just changing something? | 2010-03-15 00:17:00 Author: thekevinexpress  Posts: 256 |

They're gone now, so maybe CC was just changing something? I was working on getting the option to disable rotating headers working again. It works now as well. | 2010-03-15 00:18:00 Author: ConfusedCartman Posts: 3729 |

Seems like a hiccup and not much more. It scares me that we both are named matthew and use linux. BTW: i haven't got any so far. EDIT: lol i never noticed there was a page two... | 2010-03-15 01:13:00 Author: Deviantgeek  Posts: 386 |
| Alright, I was locked out all last night and again this morning, so I did a little research. It appears that I was having DNS issues, in that when I typed in LBPC's address, my computer wasn't converting it into IP address form correctly, and the page wouldn't load. At least this is what I think the issue was. At any rate, I changed my preferred DNS server to Google Public DNS (http://code.google.com/speed/public-dns/), and it worked! Yay. I don't understand exactly why I had to change DNS servers, but I trust Google, lol, so I think it's all better. | 2010-03-15 11:33:00 Author: comphermc Posts: 5338 |
| It appears that I was having DNS issues, in that when I typed in LBPC's address, my computer wasn't converting it into IP address form correctly, and the page wouldn't load. Yeah. I wouldn't trust your browser (particularly if you're using IE) to give you the right reason as to why it ain't working. If you want to determine if you're having a DNS failure, open up a command prompt (I'm assuming you're running Windows, but if not, then let me know) and do this... C:>nslookup www.lbpcentral.com Server: UnKnown Address: 192.168.2.1 Non-authoritative answer: Name: lbpcentral.com Address: 208.86.184.190 Aliases: www.lbpcentral.com "Non-authoritative" just means that the address is being provided by a DNS cache, rather than hitting an authoritative server, which linux tells me is... $ host -t ns lbpcentral.com lbpcentral.com name server ns1.lbpcentral.com. lbpcentral.com name server ns2.lbpcentral.com. ...but it seems those nameservers don't exist... $ host ns1.lbpcentral.com Host ns1.lbpcentral.com not found: 3(NXDOMAIN) $ host ns2.lbpcentral.com Host ns2.lbpcentral.com not found: 3(NXDOMAIN) ...which may explain some of the problems. | 2010-03-15 18:24:00 Author: Aya042 Posts: 2870 |
| lol I got "database error" when trying to load THIS page. | 2010-03-15 18:37:00 Author: IStwisted  Posts: 428 |
| I was unable to get on for the past 6 or so hours. Could not ping, but could get DNS resolved. Host just never responded. @Aya - I was thinking that since lbpcentral was on a VDS that you had to specify the DNS that way... I could be mistaken though. | 2010-03-16 00:20:00 Author: jwwphotos Posts: 11383 |
| Same here.... since 1:30pm today. Just got back in. | 2010-03-16 00:24:00 Author: Morgana25  Posts: 5983 |
| Me too, since this afternoon...! Glad to be back now | 2010-03-16 00:42:00 Author: dajdaj03  Posts: 1486 |
| im having the 'Server Not Found' already for 2 weeks | 2010-03-16 01:29:00 Author: Joey  Posts: 758 |
| Hey Joey, try this: Alright, I was locked out all last night and again this morning, so I did a little research. It appears that I was having DNS issues, in that when I typed in LBPC's address, my computer wasn't converting it into IP address form correctly, and the page wouldn't load. At least this is what I think the issue was. At any rate, I changed my preferred DNS server to Google Public DNS (http://code.google.com/speed/public-dns/), and it worked! Yay. I don't understand exactly why I had to change DNS servers, but I trust Google, lol, so I think it's all better. It worked for me, the crash today notwithstanding. | 2010-03-16 01:33:00 Author: comphermc Posts: 5338 |
| Yeah last week i changed to Google Public DNS im still having the 'Server Not Found' | 2010-03-16 01:48:00 Author: Joey Posts: 758 |
| Yeah last week i changed to Google Public DNS im still having the 'Server Not Found' Weird, man. Is it still happening on and off? | 2010-03-16 01:50:00 Author: comphermc Posts: 5338 |
| yeah. but meh Im getting use to it.. trying to find the website is hard.. but yeah... | 2010-03-16 01:57:00 Author: Joey Posts: 758 |
| i tryed for 2 hrs i gave up then everything was fine | 2010-03-16 03:27:00 Author: WESFUN  Posts: 1336 |
| I was thinking that since lbpcentral was on a VDS that you had to specify the DNS that way... I could be mistaken though. Huh? Anyways, for those having DNS resolution issues, note you can bypass that by edting your hosts file, which is C:WindowsSystem32driversetchosts on Windows, or /etc/hosts on Mac/Linux. Just add the line... 208.86.184.190 lbpcentral.com www.lbpcentral.com ...and you'll never have a DNS problem with this site again. | 2010-03-16 11:13:00 Author: Aya042 Posts: 2870 |
| $ host -t ns lbpcentral.com lbpcentral.com name server ns1.lbpcentral.com. lbpcentral.com name server ns2.lbpcentral.com. ...but it seems those nameservers don't exist... Huh? I didn't mean locally.. I meant on the VDS that lbpcentral is currently running on. | 2010-03-16 14:13:00 Author: jwwphotos Posts: 11383 |
| I didn't mean locally.. I meant on the VDS that lbpcentral is currently running on. I said "huh?" because your whole sentence... I was thinking that since lbpcentral was on a VDS that you had to specify the DNS that way... ...was too vague and ambiguous to provide any meaning to me. | 2010-03-16 15:18:00 Author: Aya042 Posts: 2870 |
| I said "huh?" because your whole sentence... ...was too vague and ambiguous to provide any meaning to me. LOL!! Yikes!! I didn't realize that I missed typing a few words in there!!:eek: So sorry, I usually don't do that!! | 2010-03-16 15:23:00 Author: jwwphotos Posts: 11383 |
| Yesterday was terrible. I kept getting server-side errors. Maybe it is ArrowChat messing this up… and the site's a LOT slower now than normal. Anyone have possible ideas as to why, besides possibly AC? (i'm not meaning to sound accusative, i'm just looking for outside input.) | 2010-03-16 21:11:00 Author: Ragfell Posts: 729 |
