[SOLVED] java process at 180%

I had a situation where my server has gotten really sloooooooow, apparently from a java process:

I have restarded and it seems to have gone away. Would be nice to be alerted when this happens again. Any suggestions how to monitor this behavior?

Hi jerryboi, would you like to be alerted about load spike? There are different monitoring tools for that like nagios.

But you have to find out the reason for this behaviour. Check your logs when this happens. Look into /opt/zimbra/logs/mailbox.log and /var/log/zimbra.log for activities. Besides check jetty logs and auth logs. Maybe syncing is causing load to spike.
