OpenJMS server seems to lock up

Intro:  
We are using two different versions of OpenJMS in production environments, .5 and .7.2.
The server is running under the RMI mode in both versions, and use it to handle Persistent Messages with Durable Consumers. 
All Sessions are managed as Client Acknowledged. 
The persistence is going to an Oracle Database.
 
The problem we have experienced is that under both versions (.5 and .7.2) we have had instances where the JMS server has locked up.
When we get a thread dump as part of killing the server after it has stopped responding everything seems to be inside core JMS code and none inside my business logic consumers.  Does anyone have any suggestions as to what I can look at/test for/etc...  The following is a subset of the thread dump from the time they went down.
