Nevermind.  Seems to work okay as long as I set "Xmx" high enough.

Subject: DQM error

Has anyone gotten an error like this when running DQM?

java.lang.OutOfMemoryError: Java heap space

I am inlining this in a process with other jobs (testing) so perhaps this does not happen when it is run standalone.
