I have the exact same issue with the same thread stack dump. This appears to occur after approximately 5000 messages go through our application. The application consists of a broker and two groups of listeners threads (different VM's). The listener groups will block for up to 5 minutes, and then one or two threads will become active again. The normal number of active threads per group is 25 however.
I know upgrading to 4.1.2 (currently using 4.1.1) or 5.x may fix this issue, but I'm not in a position to change out our software stack midstream. Any help would be greatly appreciated.
