Xen1 is in a state that its been crashing between 1 and 3 times a day. For now its biggest component was app1 which is now running on xen8. I've placed a ticket with the soc though now I doubt there's anything they can do. I'll have to contact Dell.

Change History

  • Summary changed from xen1 to xen1 + xen2

Interestingly as soon as we upgraded xen2 to RHEL5, this started happening to it as well. Bugzilla:

https://bugzilla.redhat.com/show_bug.cgi?id=429469 and https://bugzilla.redhat.com/show_bug.cgi?id=245823 and http://rhn.redhat.com/errata/RHBA-2007-0791.html

Are worth investigating, this first of which was created by us.

Additionally I've rolled back the xen rpms, and kernel to their latest FC6 version as we weren't having issues there, testing will be done on xen1.

  • Status changed from assigned to closed
  • Resolution set to fixed

The new RHEL5 kernel works as does the FC6 kernel, no more reboots.
