I have two debian lenny DOMU's running on a Centos 5.4 2.6.18-164.elxen 64 bit kernel on a HP DL380 with 20G dual processor, dual core, with a NetXteme II BCM5708.

One or other of the DOMUs' network's fall asleep until provoked into action by trying to repeatedly make a connection to a service on the vm (ssh, http ...) or by accessing the console and making a connection to something. Then when these networks seem responsive the DOM0's network becomes unresponsive (my vnc connection to the DOM0 freezes).

The DOMU use bridged networking and IP's for the DOM0 and DOMU's are DNS mapped.

Any ideas for what I might try to diagnose the issue or fix it?
