EJB error: "Unknown user exception thrown by the server"

Hi all,

I have clients accessing an EJB every 10 minutes. Once I get up to about 800 clients accessing it, I get a bunch of exceptions in the server log (attached) and I can't figure out what is causing it.

In order to simplify things, I changed my EJB code to simply loop for a while (which takes about 1-2 seconds to execute) in order to simulate an actual method call and the situation still occurs.

FYI, My bean pool is about 1/2 full (100 out of 200) so its not bean resources, my connection count never goes above 50, so that's not it. Processor usage and memory usage are both low.

Any ideas?
