Just wanted to see if there was any advice on fixing a problem that we are having with the JVM hanging every couple hours or so. Mail continues to process and desktop clients are still able to work, but if using the zimbra web app, users get a remote timeout message.

Restarting zmmailboxd fixes the problem temporarily (an hour or so).

Our version:
Release 6.0.2_GA_1912.RHEL5_64_20091020145322 RHEL5_64 NETWORK edition.

Any help would be appreciated.
