    Default [SOLVED] High CPU Load on zimbra 8.0.0

    Hello Everyone,

    I'm only noticed now that zimbra is eating away both my cores at 100% . I've looked it up and it seems that every solution I find is totally unrelated to my case.

    Code:
                                                       Ubuntu 12.04 64bit with Linux 3.2.0-29-generic on email
    
    PerCPU    100.0%    100.0%   Load      2-Core    Mem      44.8%           Swap     0.1%

    I've ran a zmcontrol restart an hour ago.

    Any help?

    EDIT: A full system restart solved the problem. It was an extra java process that was left over from last zimbra restart and for some reason it went into an infinte loop.
