Mike Matrigali commented on DERBY-5692:
---------------------------------------
without a reliable repro hard to say what is going on, which is why I suggested
running just that test/suite to see if it pops
easily in that environment. I am just guessing at why it happens on that
platform and not others. I think the way the locking
code works we don't really know why we have woken up when we sleep waiting for
a lock. If we have not gotten the lock then
we check how long we have waited and if it is under timeout we do the dealock
check.
Yes I am suggesting the kind of change you have, but would see how much longer
if at all the storetests suite takes with
it. I don't know how many expected lock timeouts, if any the suite has.

> Key: DERBY-5692
> URL: https://issues.apache.org/jira/browse/DERBY-5692
> Project: Derby
> Issue Type: Bug
> Affects Versions: 10.8.2.3
> Environment: Windows 2008, 4 CPU, ibm 1.4.2.
> Reporter: Myrna van Lunteren
> Priority: Minor
>
> I am seeing an irregularly occurring failure with ibm 1.4.2 on one machine -
> which happens to be the only 4 CPU machine and the only one running Windows
> 2008...And I've got 10.8 nightly tests running on it.
> I have not seen this with other jvms on the same machine.
> It's possible this would also happen on trunk, but we stopped supporting
> 1.4.2 with trunk and so I do not run tests against trunk with (ibm) 1.4.2.
> When the test passes, the output contains 5 identical lines 'Got a Deadlock'.
> The test failures are of 2 kinds:
> - 1 (or more?) of the 'Got a Deadlock' lines is missing
> - we get a '40XL1' error (timeout) instead of a deadlock.
> As the second situation seems to match what DERBY-715 was about, I thought it
> worthwhile reporting as a separate JIRA. We should check it's not somehow a
> regression.
