    When it happens: 30/30 players playing for 2 hours
    What it does? Kick players and stops them of joining server, when they try console gives "Connection Reset"
    What I've done to solve it:
    #1. updated all plugins, reupdating everyday to stay up to date, tried downgrading
    #2. talked with my server provicer and what he did was "increasing limits on his linux machine very high", like he's sure its super global high
    #3. When plugins are deleted error not showes.

    SOLVED
    It was becaouse of SpoutWelcome plugin - it opened .txt file with info for people before log-on, and what they did wasny clicking "Fisnish" or "Next >" to exit welcome window, they just pressed Esc. :)

    I confirm, we have rised limits of open files on debian, but this is not the issue. As it shown in txt log there. My customer is not able to add more slots because after the server is full it crash immediatelly.

    We have enough of CPU, MEM and HD resources.

    Simultanously on the same server runs other minecraft server without any problems.

    Below is dedi server configuration:

    OS: Debian Lenny x64
    CPU: 2 x INTEL XEON QC E5620
    CPU SPEED: 2 x 2,4 GHz
    CORES: 2x4
    RAM: 48 GB
    HD: 4x450GB SAS 6Gb/s,10Krpm
    SAS CONTROLLER: KONTROLER ADAPTEC RAID 6405 KIT SATA/SAS PCIe 512 MB


    What we can do more to identificate the problem ? Please check the thx log errors.

    --- As root (system wide) ---

    Code:
    cat /proc/sys/fs/file-max
    This should be a value from 36000 to 50000 or more.
    To increase the system wide maximum open files,
    edit the /etc/sysctl.conf and add the following to the end of the file.

    Code:
    fs.file-max = 49500
    Then issue the following command to activate this change to your live system.
    sysctl -p



    --- As user ---

    Also, you should update /etc/security/limits.conf for the user.
    Code:
    myuser hard nofile 2048
myuser soft nofile 2048
    Type this to see what it’s set at:
    Code:
    ulimit -a

    Thank You for the reply, I have done this couple days ago
    I now how exactly change the limit

    This is what I have in my server:




    Sorry but I have to update my post, those number which You gave me was to small, much to small.
    I've make a mistake and stupidly changed into 70000. After that I neraly crashed my whole server. Before this I had 100000 and it is cool for me.

    I run nearly 100 minecraft server on this linux server. I think I change into 900000 to avoid any further problems with linux open file limit.

    I will check if it will help.

    I've taken the liberty to contact my host about it, it's only started happening the moment we got an 8th server on the machine afaik. All other crashes before that pointed to plugins.

    If you aren't running your own VPS or dedicated server, then you can't fix it.

    You have to contact your host or start removing plugins.

    This is commonly (meaning, it has been investigated before, but not to say it is your exact problem) caused by a plugin that 'opens' files but doesn't close them properly (anywhere there is an open IO, the close statement should be in a finally clause). Some of those plugins are widely used, so I wouldn't expect plugins like iconomy or worldguard. Pick out any plugin that isn't widely used or custom and remove it, the errors should stop.

    Personal experience, we had this issue from an xray tracking plugin that happened to be coded such that it opened the file every time a stone block was broken, but never properly closed said file.
    If you know anything about java, search through the source code for those lesser used plugins for classes that are catching the IOException, there should almost always be a finally clause that has a var.close();


    Edit: hate to point fingers, but try removing foundboxx first.

    it did it again today, never really coincides with anything and nothing preceeds the report.

    I run CFBanner, CombatTag, Backup, Essentials, EssentialsChat, EssentialsGroupbridge, EssentialsGroupManager, EssentialsProtect, EssentialsSpawn, Factions, FoundDiamonds, Minequery, Nocheat, Reservations, Spout, Tradecraft-AE (I've had issues with this one before but it would always report the problems and never take the server with it, plus I got updates done for it so it wouldn't give me any more problems), VanishNoPacket, Votifier, WorldBorder, WorldEdit and WorldGuard.

    @Aprime create your own thread, its not for your error
    @Wolvereness It was becaouse of SpoutWelcome plugin - it opened .txt file with info for people before log-on, and what they did wasny clicking "Fisnish" or "Next >" to exit welcome window, they just pressed Esc. :)
    SOLVED ^
