Constantly restarting teamsite and open deploy

BENMAY

We are experiencing a problem with our teamsite and open deploy servers whereby we are required to constantly restart the server services. I am most familiar with the teamsite situation, so I will describe that one:

Periodically, between once and 3 times a week, teamsite will all of the suddent start acting odd. If you have a session already open, you can browse thru branches but any attempt to edit a file or a DCR does nothing. No windows pop up, there is no response at all except for the fact that you can move around and see the files in branches. If you have the launch page up and click the "start new session" button, a window pops up with a message along the lines of "Could not contact servlet engine." If you try to LOAD the teamsite launch page, it just hangs with the little IE globe spinning and spinning.

This is very frustrating as it constantly requires IT attention to restart the TS services, and also impedes critical business access to the tool. We are running teamsite 5.6 SP3, OpenDeploy 5.6 on solaris. Any help would be greatly appreciated! Thanks!
