How to Resolve deadlock on Apache Beehive HttpSessionMutexListener

279 views Asked by At

I still using some old school framework (Apache Beehives) to develop my web portal application.

Apparently problem is happen more frequent nowadays, I suspect it is because we received more transactions and larger XML size on single requests.

I managed to found 2006's mailing list on beehive-user mailing list [here][1] is kinda framework's bug, but did anyone know whether the latest beehive versions already cover this situation?

Following, attached the sample deadlock thread dump.
