JBoss doesnt release threads after executing MDB (out of Mem

[suhail]

Hi,
I am using JBoss AS jboss-4.0.2.
I am getting OutOfMemoryError when I send the messages to an MDB. It happens after i send 30-40 messages. What I have observed on the web-console of Jboss is that #Threads increases by some 30 whenever I sent one message to a queue. Even though message is getting consumed instantly, the thread count doesn?t come down but keep on increasing by a factor of approx 30 or more with each message. After sometime it reaches some 2000 figure and server starts giving out of memory error. If I make process synchronous (I mean not use MDB) , thread count doesnt increase.
It implies that each message is adding approx. 30 threads and threads are not released after messages are getting consumed. Can anybody explain it and give a fix ?
Please find the stack of errors below. I get either of these two stacks.

Any help will be appreciated.
Thank you
Suhail

You are reporting a JBossMQ problem (UILServerILService). This is a JBoss Messaging user forum. Upgrade to Messaging and in the unlikely case you run into trouble we'll help you :)

I couldnt find the solution in JBoss MQ so migrated to JBoss Messaging and since then things look good. Now am waiting for the new release so that I can use clustering.

(It's an old thread, but I seem to have the same problem) These may be related?

Or migrate to JBossMessaging ;-)
