[Xen-users] Kernel exceptions while running Xen?

[Rich Wales <richw@xxxxxxxxx>]

I'm running Xen 3.3 (2.6.24-21-xen) on an Ubuntu 8.04.1 server.  The
server hosts three domU's, each acting as a firewall using Shorewall.

This evening, I noticed some kernel exceptions in /var/log/messages.
(See below.)

The dom0 and all the domU's did NOT crash and kept on running.

Any suggestions?
