Hi all,
 
I was just wondering if some of you have experienced similar problems with V440 machines ?
 
One of my customers is having several V440 and one of them has already rebooted unexpectedly three times over a month. Nothing can be found in /var/adm/messages, everything looks fine, no warnings nor errors, and from one line to another I suddenly have the begining of a
reboot !?!? I cannot find anything neither in other log-files pointing to a potential serious problem or warning !?!? The system is currently part of a test-cluster and when I came in this morning a service group had failed-over during the night and logs tell me the node went down.

The customer told me they have already had some unexpected reboot on V440 on site for some of their own customers. Seldom however.
 
So ... have some of you experienced similar behaviour ? The cluster has some other V440 with identical configurations (hardware, firmware, patches and software), but only one V440 is unstable !?!? and reboots, even if seldom, apparently are random (I have so far not been able to identify any possible pattern).
 
The V440 has 4 CPUs (1062 MHz), 8GB RAM, connected to a SAN (using QLogic 2300 cards), 4x36GB internal disks, OBP 4.13.0 and as far as I can see everything looks fine !?!?
