In reply to a comment by Karl Wright:
Derby has a huge number of threads waiting on being able to modify or update a number of table
rows.  Meanwhile, one thread seems to be alive and is updating hop count data.

My suspicion is that there is indeed a bug in Derby, but it's the hopcount logic's intensive
use of database access that exacerbates the problem.  I suspect that jobs that do not deal
with hopcount at all will not fail readily.

In any case, you can easily change the Quick-Start's properties.xml file to use PostgreSQL
instead.  The online build-and-deploy doc explains how.
