    I disabled SNMP and Logger, but doesnt have any effect. What can I do to fix this problem? In zimbra 5 I didnt have this problem.

    Someone can help me?

    Regards.

    I had this odd problem when I upgraded to v8. Everything I tried didn't work, until I rebooted the host itself and it magically fixed itself. No idea why, but it might be worth a try.

    I already have disabled Logger and snmp. In the sysctl I put this:

    vm.min_free_kbytes=16384
    vm.swappiness=0
    vm.vfs_cache_pressure=50
    vm.min_free_kbytes=16384
    vm.dirty_ratio=10
    vm.dirty_background_ratio = 5

    In cron, I set the zmstatuslog to 23PM. But nothing working. I rebooted this server many often, without success.

    Do you change some configuration? Some sysctl? In zimbra v5 I didnt have this problem, but v8 I dont know what can I do. I think that the solution is a downgrade to v5.

    Is this a memory problem? Can be this the cause of my problem?
