Large Virtual Memory after Derived Value Calculation

Hello,
I've recently been calculating some surface integrals over a wide range of parameters. I have successfully run a parametric solution with 21x4 parameter combinations, and now I'm trying to calculate a few different surface integrals for each parameter combo.
Fortunately, the surface integrals only yield a single value, so after all is set and done, I should only be generating a few kilobytes worth of table data.
Here's the problem- COMSOL seems to be stacking up more and more virtual memory as it goes along. I made it through about 80% of my surface integrals before my computer ran out of virtual memory on the hard drive at 45 GB.
So how can I get COMSOL to clear out that 45 GB? Sometimes I've noticed that if I ask COMSOL to do another calculation, sometimes it reclaims the VM. So I did a dummy study but it only dropped to 40 GB. Is there a node I can delete to reclaim this memory? I've already saved all 24kb of the table output that was successfully generated.

I repeated the dummy study a few more times and its now down to 25 GB. What's going on? Why is this even working? Is there a better way?

This behavior sounds strange. I suggest that you contact COMSOL Support and send them the model for which this happens.
