Another memory dump

I have a server wich bluescreens at irregular intervals (5-30 days). It is an HP ML 380 running Veritas Cluster and Exchange. It is one of the nodes in an active/passive Exchange-cluster in production. THe other node is configured identically, but has never bluescreened. I would be very grateful if anyone can help me out, I have noe experience analyzing dumps and can`t find any useful information from it. Microsoft support may be the best bet but I would like to try this first!

The dump is as follows:

available get the stack trace.
