Specifying pool size for message driven beans

[jreifsnyder]

Hi all,
I am creating a message driven bean at startup, and posting messages to it during operation.

I have tried every configuration parameter I can find, but I cannot adjust the max pool size -- which is currently set at 15. Performance hits a wall at a set message/sec level and we get a backlog, obviously. Is this parameter tuneable? We are using JBoss 4.2.3 with JBM.

Any help for a messaging newbie would be greatly appreciated. Thanks!
J
BTW, I can post all the definition info if you need it.

Forgot to mention: we are posting messages on queues and we have the connection set for "slow consumer" by necessity. This is why we need more than 15 beans in play.
Thanks,
J
