    Default [SOLVED] ZCS 6.0 - zmlogger service using very high CPU

    I have been running Zimbra for about 2 years now and have upgraded periodically throughout the 5.x code stream. I just upgraded Zimbra from 5.0.16 to "Release 6.0.0_GA_1802.RHEL5_64_20090830141723 FOSS edition" and have read about the changes to the zmlogger process.

    My issue is that since the upgrade, the zmlogger process appears to be constantly using excessive CPU. Here is a typical output from the top command and this is pretty typical (going from 99% to 119% with each cycle):
    Mem: 2051248k total, 1964088k used, 87160k free, 23248k buffers
    Swap: 4095992k total, 0k used, 4095992k free, 630704k cached

    PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
    6894 zimbra 25 0 54976 8772 2436 R 99.9 0.4 2:21.38 zmlogger

    I have attached the output from the commands recommended by Zimbra from zmlogger troubleshooting section. Also, the /var/log/zimbra-stats.log file is growing extremely quickly and doesn't appear to be getting "logrotated".

    As much as I like the new functionality, I think I may have pulled the trigger a little early upgrading from 5.0.16 to 6.0.

    Thanks for any insight regarding this issue....
