Oh, yes, millions upon billions of lines of wonderfully obscure Java stacktraces that
reveal little more than "Lost connection to database" for every couple of thousand lines. 

Everything works fine most of the time, then randomly some queries will get slow, and
eventually the connections will drop. Rinse and repeat.
