    Hello,

    I am experiencing crashes on my server. The crashes usually happen once every 30 mins. They are short, and the server usually starts back up instantly. If it helps, i have not had these crashes before, and i am now experiencing them a few days after the installation of a custom vote plugin.

    Here is my error log. Any help is appreciated.

    me.neatmonster.* seems to be causing it all.

    Can you list your plugins?

    That error message is coming from a custom vote plugin that was made for my server. I deleted the .jar due to a bug, and it seems that after that, the crashes started to occur. Could it be that the plugin is still sending requests to the mySQL server and causing crashes?

    The voting php script is hosted on a seperate apache php webserver, and it communicates from there to the mysql server.

    Oh, and my plugins are:

    ButtonWarp
    Citizens
    ColoredSigns
    ColorMe
    Essentials
    EssentialsSpawn
    LWC
    MagicCarpet
    MobDrops
    MuddersMilk
    MyWarp
    NoCheat
    NoPearls
    Prefixer
    SimpleHelp
    Teams (Custom Plugin)
    Timedmessages
    WorldBorder
    WorldEdit
    WorldGuard

    Yes, I saw the mySQL errors too, what do you think it might be?

    Getting more errors..

    Do you happen to have any other mods on your server?

    As a note, these crashes did not happen before 1.1 R4, so perhaps it could be an issue with the new build?

    CRAZYxMUNK3Y

    I can not see any reason for those plugins to be causing it, also, if the separate apache server, or for some reason you still have the folder (with a php or config on it) on the server, that could be causing to errors, yes.
