Kathey Marsden commented on DERBY-4239:
---------------------------------------
I did another thread dump and confirmed that as you suspected, it was not hung
but still looping.
The thread doing the checkpoint, is set as a daemon thread, so should have
terminated when System.exit() was called. I am not quite sure why it didn't
with this particular run, but it doesn't look like a Derby issue, so I won't
pursue it for now.

> I saw corruption on z/OS with the storerecovery tests and 10.5.1.1. The
> failure comes in oc_rec3 trying to connect to the database, but the actual
> problem seems to have occurred with the prior test oc_rec2. The problem is
> somewhat intermittent, happening approximately 1/4 times. I extracted the
> case from the harness and will attach the reproduction and run the script
> repro.ksh. The script will loop up to 50 times until it gets the failure
> which looks like.

> I ran it with 10.3 and it completed all 50 iterations, so whether JVM or

> have run tests many times before on this machine using in the 10.5.1.1
> release and the same jvm and have never seen this failure, so am looking into
> whether maybe something changed on the machine or environment.
