EntityLockMonitor won't help you then. JBoss CMP and BMP should try to update beans in the order that they are accessed. Also not that any finder calls within a transaction will cause a synchronization events of all beans changed within transaction.

Bill,
Sadly, I'm getting DB deadlocks. Sometimes they freeze the whole system, and other times they don't. I'll have a look at the entity lock monitor. Sounds good.
Thanks,
Jonathan O'Connor

I don't remember, but I think my EntityLockMonitor is in 3.0.6. Uncomment this MBean within server/<your-config>/conf/jboss-service.xml


It has a number of utilities for debugging deadlocks. See our for-pay doco for more info.

Are you getting DB deadlocks or JBoss deadlocks?

I just started stress testing our JBoss server. I run our unit tests simultaneously in two different windows. However, I'm getting a number

Does anyone have any bright ideas how I can track down the problem?
In case its relevant, JBoss version is 3.0.6 and I'm connected to a

ASE 12.0 DB using JConnect 5.5 JDBC driver.
