Where is the deadlock culprit?

Wed, 03 Dec 2008 10:34:54 -0800

I know there are many smarter than I here who like a 5-second challenge ;-) Anyone care to diagnose this jstack output from a deadlocked app?
The app is WO 5.3.3 fully embedded running on java 1.5.0_16 on Leopard server 1.5.5 on XServe G4. This instance had 48 sessions when it began to refuse logins. It would seem that the deadlock was related to session store checkouts ..... any thoughts on prevention?
