Reported by Dave Newton:
Using a fairly recent Torque (3.1, maybe 3.1.1) for some reason I started getting HUGE values for one of my NEXT_ID columns and the QUANTITY column.
While saving new objects to that table I got OutOfMemory exceptions. When I made the NEXT_ID and QUANTITY values saner the OOM exception went away.
I have since turned off cleverquantity...
