Jboss Cache stuck thread

Alex Alex Newbie

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:

 

Name: pool-2-thread-339

State: RUNNABLE

Total blocked: 1  Total waited: 0

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
