Admin panel logs me out

Seems my admin panel session times out really fast.

I can be working in the admin panel and suddenly end up at the login screen. Fastpath web chat is also behaving weird. Short time into a conversation it says that the agent closed the session.

It sounds like a date/time error, but its not.

I am running Openfire 3.6.4 / Windows Server 2008 x86 Enterprise in a Virtualbox.
