Strange limits on Parallel RAM Usage by Compiled Standalone

I have a MATLAB-compiled standalone .exe on a desktop with 20 cores and 32GB RAM. Because of the ample resources of the desktop, I tried to launch several instances of the .exe in parallel. I find that any more than 2 instances running in parallel will crash with memory allocation error messages. However, each instance on its own consumes no more than 4 GB RAM according to the Windows Task Manager. With 32GB RAM total, I reason that 4 instances should easily be able to run side-by-side.
Any theories as to why I am limited to so few instances when I have so much RAM to spare?

I don't know, either -- simply wondering if might help uncover what's going on if symptoms were to change is all...
