Hi,

I'm having issues with a stuck thread on JbossCache put operation. After examining the thread dump I've found the following thread which seems to be stuck:

All of the other reading threads are in a blocked state because of this thread.

Other details:
- I'm using Jboss 4.0.5, Jboss-cache 1.4.1 SP10.

Any idea about what might be the problem here?

Thank you
