We upgraded a cluster of 3 x CUCM Servers that were running 6.0.2 S/W version to version 6.1.2.
These are HP DL380 G5 boxes.
After the upgrade ASR (Automatic System recovery) caused two of the three Servers (one Publisher and one Subscriber) to reboot about once or twice a day. We then upgraded to 6.1.3 hoping that would resolve it. Yet the same problem.
The two servers (one Pub and One Sub or say one First Node and one Subsequent Node as the new terms are) with the reboot problem are in Site 1 and the stable Sub is in Site 2 about 20 Kms away. AC Power was elimintaed as a problem because this Data Centre has UPS and bucket load of CORE CAT 6500 switches and many many many other Windows / Linux Servers with no problem.
We disabled ASR and that just prevented the restart of the servers, but the servers just hung. When they hung we could still get to the servers through the ILO and click on reset to restrat the servers again.
The Pub abd one Sub never hang at the same time, but at different times.
Site 1 also had a CUPS Presence Server running 6.0.2.
The interesting thing is that we rebooted this CUPS box and we haven't seen the problem for 1 week now.
I wonder if anyone else has seen this symptom.
