Because of the way that OS X allocates virtual memory, it is not
unusual for programs to show very large amounts of virtual memory
in use. The virtual memory isn't really occupied.
This morning real memory usage by the license manager is up to
685 MB.

3.2GB VM is not unusual? It's unusual here for actual users of IDL to require
that much VM (obviously some do, but not many). The license manager should be
tiny.

I'd say so. Ours (on Linux) is currently using 28MB VM, 2MB resident. It's been
running since 29 May and according to the log has served nearly 25,000 licenses
since then, so it's not exactly been sitting idle.
