The above message contained the following:

I just went over all the changes in going from LDM 6.0.14 to LDM 6.2.1.
I didn't see anything that could account for the differences in the RSS.

The 6.0.14 LDM should have a VSZ around 800 MB if the operating-system
it's running on counts process-size the same as the one with the 6.2.1
LDM.
