Knut Anders Hatlen commented on DERBY-5108:
-------------------------------------------
There may be other issues than the istat daemon coming into play here. I see
that RawStore.stop() doesn't wait for the checkpoint to complete if there
already is a checkpoint in progress, so there may be similar problems in that
code. A related problem with checkpoints reopening containers during shutdown
was fixed in DERBY-4920.

> Key: DERBY-5108
> URL: https://issues.apache.org/jira/browse/DERBY-5108
> Project: Derby
> Issue Type: Bug
> Components: Test
> Affects Versions: 10.8.0.0
> Environment: Windows platforms.
> Reporter: Kristian Waagan

>
> The test AutomaticIndexStatisticsTest.testShutdownWhileScanningThenDelete
> fails intermittently on Windows platforms because the test is unable to
> delete a database directory.
> Even after several retries and sleeps (the formula should be (attempt -1) *
> 2000, resulting in a total sleep time of 12 seconds), the conglomerate
> system\singleUse\copyShutdown\seg0\c481.dat cannot be deleted.
> For instance from
> http://dbtg.foundry.sun.com/derby/test/Daily/jvm1.6/testing/testlog/w2003/1078855-suitesAll_diff.txt

> 1=system\singleUse\copyShutdown\seg0 2=system\singleUse\copyShutdown
> used 205814 ms F.
> Maybe the database isn't shut down, or some specific timing of events causes
> a file to be reopened when it shouldn't have been (i.e. after the database
> shutdown has been initiated).
