Still having some problems with this. I've now had it happen on a couple
different xen servers. I thought it was related to a specific domU, but
the latest event did not involve that one. 

Basically the server hangs, but network activity, even on the domUs, is
still there. IE, I can ping both the host and the VMs, but I can't do
anything on the host or the VMs. 

The latest one took a week before it popped up. Happened sometime
yesterday or last night. Since pings still work, I'm not sure when it
happened.

Any suggestion on how to troubleshoot this?

Thanks,
James
