I think this might be related to the 3.1 resets but what can I do to collect more information to help resolve this issue or if its a known issue would someone please point me in the right direction. The system has 8GB RAM and is not swapping at all I have 50% of free disk on each JBOD that I am using as a cache store. I am only logging to cache.log so I do not hae any log file size issues.

Your issue appears to be this open bug:
