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.
At present xen1 is running on 2.6.18-53.1.4.el5xen, I'm going to try 2.6.18-8.1.14.el5xen.
Jan 9 03:10:56 xen1 iscsid: Nop-out timedout after 15 seconds on connection 1:0 state (3). Dropping session.
Jan 9 03:11:18 xen1 iscsid: connection1:0 is operational after recovery (3 attempts)
Jan 9 03:14:04 xen1 syslogd 1.4.1: restart.
Jan 9 03:14:04 xen1 kernel: klogd 1.4.1, log source = /proc/kmsg started.
Running 2.6.18-8.1.14.el5xen failed. back to 2.6.18-53.1.4.el5xen now.
Interestingly as soon as we upgraded xen2 to RHEL5, this started happening to it as well. Bugzilla:
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.
The new RHEL5 kernel works as does the FC6 kernel, no more reboots.
