Comment 9 for bug 1152815

I'm having a very similar issue with 0.8.0-rc1 and Hibernate 4.2.2. When I start my application and let it sit idle for over an hour, the next connection I try to acquire hangs with the same stack trace as reported, included below. I have not narrowed it down to exactly how long things have to be idle, but I know at 45 minutes things work fine, and at 90 minutes they hang. I've added a connection hook to my system and I'll see if it provides any useful information and report back.

here's the (partial) stack:
