[Xen-users] Fwd: [Bug 1303] sometimes centos4 domu deadlocks

["Jerry Amundson" <jamundso@xxxxxxxxx>]

Thought I would throw this to the group in case any one has ideas. I'm
stumped and my boss is telling me to try it on ESXi, so the writing's
on the wall...

The dom0 is CentOS 5, fully updated, running Xen.org 3.3.0 installed
from my rpms. It's using DRBD paritions for it's two domU's:
1. Centos 5 2.6.18-92.1.10.el5xen, file/web server. Runs perfectly.
2. Centos 4 2.6.9-67.0.22.ELxenU, database development. Runs horribly.

More details in the bug, but basically the dom2 machine runs fine for
a period of a day or so, but up to as much as a couple weeks, then
completely locks up - no network, no xm console, no xm shutdown.Only
option is xm destroy, and xentop, virt-manager, etc. show heavy CPU
usage in both dom0 and dom2.

Tia,
jerry

------- Comment #15 from jamundso@xxxxxxxxx  2008-08-17 12:54 -------
Dom0 is 2.6.18-92.1.10.el5xen on Xen 3.2.1 now. (CentOS 5)
"echo 3 >/proc/sys/vm/drop_caches" is unrelated.
CentOS 4 domU locked up twice in the past week. I took dump-core of it today.
