We are experianceing a strange problem about our MDB.
We have a workflow engine with one MDB some session beans and entity beans.
Suddenly a SpyJMSException occurs and it keeps on coming every minute from that
moment till you restart the server.
There is no cause mentioned with the stack trace. It only says Connection
Failiure. The stack trace is given below.
This has happened on Jboss 3.2.5, 4.0.1 and 4.0.1 sp1.
Looks like for some reason queue gets disconnected.
Can anybody throw light on this?
