Comment edited by Karl Wright :
---------------------------------------------------------------------
My Derby crawl did not finish either.  Even worse, it locked up badly enough so that I had
to stop and restart the crawler process to get into the UI.  So clearly there's a database
issue of some kind.

You can always safely restart the process; when you do that, the job should complete aborting.
 But that's immaterial, because Derby seems to be deadlocking internally in some way during
the crawl.

I strongly urge that you give up on Derby and use PostgreSQL.  The performance is better and
it won't deadlock in this way.

Meanwhile, I'm going to try and figure out what Derby thinks its doing when it hangs in this
way.
