    Hello all,
    i am writing this thread to ask for help on a problem that will decide whether or not my server will stay alive. My issue is that every 1-3 hours my server will stop and disconnect all players however, the actual server will stay up and when players try to connect it says 'Read Time Out error'. I have a host (Brohoster) and have asked them for advice and they suggest that it is bukkit and not them. I did some testing and removed all plugins for 15 hours and it did not crash, however only about 3 were on at this time. This error happens when 10+ are on which suggests the issue that i may be running out of memory. Honestly this is my last hope and if i am unable to reach an answer i will have no choice but to close my server down. All in all, have a nice day.


    CRAFTBUKKIT [1000]

    PLUGINS: AutoAnnouncer, Bookworm, BorderGuard, Essentials, Factions, FoundDiamonds, HeroicDeath, KiwiAdmin, LogOres, MagicSpells, MCDocs, MCMMO, MineBackup, MonsterBox, NoCheat, Permissions, ServerSave, and finally WorldEdit.

    Anyone? Please i really need help.

    I have the very same issue since CB1000.
    It has NEVER Happened before and no RAM is not an issue since I run a local server with 10GB ram dedicated to it.
    For the past days i have been testing and trying to figure this out.. here are some observations:

    -It started after CB1000, last build i used before that was 957.
    -It's random, happens with 20 people on after the server ran for 8 hours and the same time it happens 3 mins after a restart with NO players on.
    -At no time was RAM even close to maxed out, i've been running the server with the same settings for months.
    -Plugins have no effect, I've stripped won literally every plugin and it still happens. This is a bitch to test due its randomness.
    -As above, there is NO error in the console, all that happens after is "Read timed out" in the console.
    -It was still present in the last CB i tested (1031)

    Now for now i have rolled back to bukkit 957, which has now been running fine for 13+ hours.
    This makes me think it is indeed something with bukkit and i gladly help in anyway to find out the cause for it.
    I will do more testing tonight and see if the error really is gone with 957.

    I suggest you do too try 957 again Rowling, it shouldnt really be a problem with the plugins you have.

    Oh look, this problem seems to be well known by now:
    A thread with some the problem and some solutions.

    Well this is serious, any word from a dev perhaps? I saw the issue was posted on leaky.. with no reply.

    I have not come across anything from a dev about this. I wish craftbukkit would at least give me an error or some warning towards what is happening.

    I can tell you how did I solve that. I'm not telling how to SOLVE, just how I solved it, so not sure if it works.

    1- Disable Nether if you have one using Notch code (I mean allow-nether=false, Multiverse seems fine)
    2- Change Permissions for PermissionsEX or just disable Permissions
    3- Change BigBrohter for LogBlcok or just disable BigBrother

    Solved (at least for me :-P)

    hmm interseting. Im not sure what the first one will do but i will try

    what does permissionsEX have over permissions?
    Logblock is lighter but the issues happens even with bigbrother removed.

    Thank you. If the server crashes again i will try your steps.

    Im not saying permissionsEX is better than permissions, or something. When i was trying to solve the error, y just read a lot and seems like permissinos 3.1.X was causing that error to some poeple.

    Im not sure what fixed it, i just try all those 3 steps at the same time and it stopped hapeens. And it stop the error, so now i am just using Multiverse (soon), Logblcok and PermissionsEX and all seems right. Not even getting the "can't keep up" message.

    By the way, if you haven't try this yet, try to run the server with no plugins. If it goes Read time out again maybe you have network issues or corrupt map.

    All is just guessing and telling you what i read in other places. I can't tell you why th¡s should/shouldn't work. It just work'd for me :)

    Luck solving the problem.

    Didn't work. The CPU usage of the server drops to 0% and hangs. It is probably the map. Let me load a blank map and see if it crashes.

    Switching to a newer version is your best bet. I had this issue also and read lots of forums with lots of people having this exact same issue and a lot came with the solution as switching to a newer version of Permissions. I chose PermissionsEX and it fixed for me.

    Hope this helps

    So, in a new world, with no plugins, still getting "Read time out" ???

    A new world with no plugins runs fine. It has to be one of the plugins. One of our servers admins combed through alot of the code for the plugins. We re-wrote alot of code.

    As of now the server is running great. Reduced CPU and RAM usage.

    Edit: Still Happening.

    When a player joined the entire server locked up. The CPU dropped to 0.

    what would cause this?

    I will say player joining has nothing to do

    1. Code:
      2011-07-30 16:51:[B]17[/B] [INFO] DaxNagtegaal [/77.164.113.138:51001] logged in with entity id 4072078 at ([Survival] 598.84375, 67.0, 822.28125)
      2011-07-30 16:51:[B]52[/B] [INFO] Read timed out
      I can't help with, that sorry :'(

    Thank you trollkemada :(

    I know a player joining probably isn't the reason but its the only thing i can see.

    I was Able to reproduce the error. The server hangs and the cpu usage drops to 0. If i type into the console as it crashes the server will continue and not drop everyone.

    Im confused How is this possible?
    What can i do to prevent this?

    Update: If I minimize the console and make sure the console doesn't have focus (left clicking the desktop or another application); craftbukkit will run fine.
    I need to find a better solution.
