I just noticed that the process sesinetd (the license server right?) uses 35GB virtual memory and even though I quit it it starts up again. Even after a reboot of my computer. That doesn't feel right to me. Anyone got an idea?
I'm running the latest version of apprentice on a Macintosh.

I'm seeing the same thing, but i have no idea what that really means, after all those processes are never actually going to access that virtual memory.

This was discussed here:

In short, don't worry about it. Not that much memory is actually being used.
