Very high CPU usage of mailboxd after upgrade to 6.0.8

[buk]

Hi.

On friday we upgraded from 5.0.15 to 6.0.8 and since then the mailboxd uses one CPU of our QuadCore box. On its own.
After (re-)starting Zimbra it acts normal but after a while it starts using 100% cpu and grabs more and more memory until an OutOfMemory occurs.

Does anyone have similiar issues and can provide any help where to look?

I decreased the mailboxd heap size to 20% as we have a 4GB system.

Running on RHEL5.

Thanks for any hints.

Can you show your output of "top" and "top -u zimbra" command?

See the output from top -u zimbra above when the problem occurs.
