Xen users - Mar 2008 - Guest''s network stops working after a while

I''ve installed the latest version of CentOS/Xen on a server and have
created 3 guest OSes (all using Cent OS). I''ve noticed some strange
behavior with the network connections. If a guest''s network is not
accessed for a while (meaning it''s idle - no incoming or outgoing
connections) then the network stop responding (ssh''ing from the host
server seems to re-engage it) to incoming requests.

I have tomcat running on one of them. If the network is idle, tomcat
will stop accepting connections until I ssh into the server and all of
a sudden, tomcat responds. Very strange.

Anyone else have had similar problems?

Thanks

Jean

Yes, a thread spoke about that few weeks ago. Look for the subject  
"[Xen-users] domU network has sleeping sickness".
Maybe a duplicated MAC address.
