    Have big issue with my server. Situation:
    Online - about 30-40 peoples, all build, chatting, etc. All looks fine.
    BUT! Server got some shit, like time stopped. All player got "Timed out" error. And after 20-30 sec all can join back at server.
    I see this in console:
    (I think AuthMe works good and bug coz all players strangely out)
    As you can see, server keep up and not crashed, but it freez, drop all players and keep work.

    About my server:
    [INFO] This server is running Craftbukkit version git-Bukkit-0.0.0-653-g9992fff-b677jnks (MC: 1.4)

    kzp [~]# uname -a

    Be happy if someone know how fix this.

    So your basic error is this
    I am not an expert on errors, but i will say to try and removing AuthMe Plugin and see if that helps.

    I think its not a good way...
    All players begin join on another player and steal resources and many other. Anarchy.

    I HAD this too!!! The BROKEN PIPE stuff! are u using McMyAdmin on linux to host your server?
    This could be a CPU usage issue, i was using McMyAdmin on linux and it was taking up 90% of the cpu! i removed mcmyadmin and havent had any issues since.
    if u are using linux simply type "top" without quotes into the console see if a lot of your cpu is getting used.

    All my stats here:

    As you can see, my CPU never overloaded (I mean, never get 200% load) and I think its a not hardware problem.
    No, i`m not use any staff to launch my server. Console only.

    Updated to 733, still freez.

    where is the server hosted? and on what connection?
  17. Offline


    My own server. 100mb\s.

    I think it is the best if you go test some things yourself.

    Like can you still connect/ping to the server when everybody disconnects.

    Else make a backup of the server and test without Authme or with some other offline authentication plugin

    When this shit happens, java process got STATE "umtxn". When minecraft works fine (no errors, no freez, etc) process have STATE "ucond".

    When freez comes ngrep shows that FreeBSD receives packets from players, but does not response. I can see incoming traffic on minecraft port, but there is no outgoing traffic. Another daemons (nginx, apache, exim) works at this time just fine.

    I tried to look what Java process does (system calls, threads, etc) with truss and ktrace, but all I've got was "segmentation fault" error after 2-3 mins of work.

    i think im having this exact same problem
    i use xauth instead of authme, and winserver 2003
    but exactly same problem
    but mroe frequently ;[
    >EDIT: i ran my server without the wrapper, took some arguments out of the command line, added the xginc argument, also took off the -server argument, which i will test later. and everything seems fine now.
    i know that java had an update about right before this mess started so it was either the wrapper i was using. or the java update.

    The server that I help manage has never had a problem with false joins. Not once.

    And we have hundreds of players and around 20 on at a time nightly.

    tha d0ctor

    im having a very similar problem with read times out, it appears to be a MCMYAdmin problem
  23. Offline


    could you paste here all arguments you use to start minecraft? i'll chek them out on my server...

    we don't use mcmyadmin, because it does not have native support for BSD sytems.

    McMyAdmin does have BSD support (It is tested against FreeBSD, but support for it is unofficial at the moment) - If you're getting Mono sat at very high levels of CPU usage, update mono to 2.10.x (Some 2.6.x versions have a bug that causes high CPU usage whilst performing garbage collection)

    :D have to say i take what i said back, i am even trying the server with just my run.bat file, no wrapper
    SET BINDIR=%~dp0
    CD /D "%BINDIR%"
    "%ProgramFiles%\Java\jre7\bin\java.exe" -Xincgc -Xmx1G -jar craftbukkit-0.0.1-SNAPSHOT.jar
    as well as trying \Java\jre6\bin\java.exe

    seems every 10-5 mins just about everyone gets
    name lost connection: disconnect.endOfStream
    and usually the server does a
    Read timed out
    Connection reset
    error beforehand

    Ok, So.
    Last day we have minecraft running with this args:
    We had 50 online today with no problems and CPU usage is OK.
    I hope from this moment minecraft will go better with no problems...
