Yes, I have, we have done a lot of tests, it took a bit of time.
While testing, we got the server freeze without xen kernel at all, so xen is
not the problem. It turned out, that the server is very stable, when I
disable network interface bonding.
I found a bug report in the novell bugzilla:
https://bugzilla.novell.com/show_bug.cgi?id=278475
do you also have bonding enabled on your dom0's interfaces?
kind regards
Sebastian
