It could be a JBoss Remoting issue. What version of JBoss Remoting are you using? Also please post your issue to the remoting forum also, you may get a quicker answer from there.
Thankyou for your response. I will post the issue to JBoss Remoting forum.
The JBoss Remoting version is 2.2.2.SP8 the one that came with JBoss AS 4.2.3 GA (haven't upgraded the JBoss Remoting version).

The correct remoting version for JBM 1.4.2.sp1 is 2.2.2.SP11. You can try that version and see if problem still exists.
Also the latest release for AS 4.x is 1.4.5.GA with remoting 2.2.3.sp1. You can also try it.
Thanks for your suggestions.
The JBoss 4.2.3 GA default Remoting package was upgraded to JBoss Remoting version to 2.2.2 SP11. After running the test again I saw no change in the behavior i.e. the worker thread count reaches a high water mark and stays there. All the Worker threads remain in waiting state after all clients have disconnected. Even after there is no activity on the server for over 20 minutes none of the Worker threads are closed.
I tried to download JBoss Messaging 1.4.5 GA but the zip file that gets downloaded appears to be invalid/corrupted. Download completes within a minute but WinZip reports corrputed file on attempt to open the file.
Hi are you downloading from here:
I tried on Linux the zip file is ok. I'll try it on Windows later.
If it's corrupted, i'll update it.
Thanks Howard, I was able to download the JBoss Messaging zip file on Windows platform and this time around it was correctly downloaded.
I upgraded to JBoss Messaging 1.4.5.GA and JBoss Remoting 2_2_3_SP1 however there is no change in my observations. The Worker Threads still remain in memory after a period of no activity on the server.
By the way I thought of mentioning that if you try to run the Topic example included with JBoss Messaging by running the build.xml, it refers to a file examples.properties that is missing from the examples directory (in the downloaded zip file) . I am not sure if this was excluded on purpose.
Please do let me know if you would like me to try something else and thanks again for your help.
