Kathey Marsden commented on DERBY-4915:
---------------------------------------
Would it cause problems with the nightly output parsing if we always printed
out a list of the remaining files when we have to retry. It would be
interesting over time to see if it is always the same ones and since we don't
really understand the root cause it might help in future diagnostics.
I seem to recall user cases where we had to tell them to sleep before rapidly
rebooting a database after shutdown. It would be nice to have something to
call to see if the shutdown is really complete or better prevent shutdown from
returning until we are really shutdown.

> This is on a machine that I've been able to arrange for a windows machine on
> which to run the tests for 10.7 nightly, but this is not a new machine. So
> perhaps the disk - being older - is a little slow in deleting? Perhaps the
> check can be delayed, or redone if failed first time.
> I'm still investigating, checking on hardware settings. The disk scan showed
> up healthy, and multithreading is not on.
