Hi Scott,
See my most recent reply at the bottom. It does seem to be a GC issue, and I attached a couple of gc logs from the most recent occurrences. Unfortunately, I'm not sure it's the Hibernate cache, since we do not have any second-level cache enabled. Or, could it be elsewhere in Hibrnate? It seems to me from the gc logs that something is stuck, since full GC's are running continuously when the problem occurs. It's as if they are running, but failing, and so running over and over again. Where might I be able to look to try to find the problem?
Thanks for your help once again!
