~5MB/map, 512MB RAM, ~2GB swap. I'd expect a segfault (or an exception at least) if I was overloading the memory/swap, and CPU would drop if it was running out of physical RAM and swapping too much. > I haven't the slightest clue.

No consistent pattern. Both machines are x86, non-nvidia graphics cards (which probably isn't helping). But, score at least one working setup (yours) as a fully functional combination. > You might try as was suggested to upgrade your kernel.

I'm reluctant to make major modifications to a system that I'm using to do research in the middle of a project (I've had 2 independent backups fail me at the same time). Particularly for a problem that isn't predictably reproducable, so I wouldn't know if an upgraded kernel/module had actually fixed the problem or not (it could be done w\ testing livecd distributions or within a vm, or trying to get a debug build of pymol talking happily to a debugger, but at a certain point it becomes more trouble to track down and fix the bug than it does to deal with it).
