Process' are taking over

[newmember]

I have zimbra 5.014 running on Ubuntu and at least twice a day the box goes crazy proccessing. It certainly looks like the zimbra process.
Zimbra runs the CPUs and the DSK at max for 10-15min.
While its doing this, IMAP is slowed to nothing.

How do I determine what zimbra is doing?
I just happen to notice that zmgengraphs takes alor of CPU and DSK time as well, is here advice for reducing the computing time for this?

Thanks


BTW the only application running on this box is zimbra so those are all zimbra java process'

Hi!

Please see this thread, could it have something to do with it (since you are running Ubuntu as well...)? Zimbra on Ubuntu 8.0.4 - severe issues
You could also vote on the bug!

This is really similar to the issue I'm having. Here it is.
