BungeeCord CPU overload

Discussion in 'BungeeCord Help' started by FreeWall, May 15, 2016.

  1. Since 1.9.2 bungeecord support was released, my bungeecord server is getting 100% CPU usage several times during the day. No DDoS attack or bots is detected, no error in log is appeared.

    In htop (linux debian) there is like 8-10 instances of bungeecord using 100% CPU, so 600% overall.
    Server cannot be stoped regularly from bungeecord console, because it's not responding. I have to kill the process with SIGKILL flag.

    Using latest bungeecord build 1155.
    Server has around 40 players online, bungeecord instance has allocated 1GB of RAM.

    HW specification:
    Code (Text):
    Intel Xeon E3-1230 (4 cores, 8 threads)
    RAM 32GB
    HDD 1TB
    Bungeecord plugins:
    Code (Text):
    BungeeTabListPlus, SkinsRestorer, CommandControl, ServerListPlus

    Graph of system load in a day, there is several peaks (overloads):

    Are you on the latest Build of BungeeTabListPlus? It's quite cpu intensive.
    Try running Bungee without XmX.
    If it doesn't help, get a VisualVM report as requested by Jamm14.
    There are plenty tutorials how to make one in the internet.
