I finally found our leakage, but havent been able to fix it yet. It seems java.lang.Thread objects created by JBossMQ do not get garbage collected for some reason.
Hi,
I'm using JBossWeb1.0.0GA and hibernate for DB activities and Spring framework for transactions. I'm getting "No Managed Connections" when I'm testing some update/insert operations which happens only in the linux platform but not on a windows platform. Is JBossWeb having some compatibility issues with RHEL4.0 or is it something to do with the configuration parameters?
Please try to add following tag to your *-ds.xml file :
<track-statements>true</track-statements>
This gives you hints where unclosed connection occur.
