Does SGI OS 3.3.1 lock shared memory regions in core? I have some evidence that it does. I'm using the FAST visualization environment. It puts solution data in shared memory. Solution data is big. If I leave the solutions in shared memory and do something else that requires a lot of memory (but no the solutions) I get a ton of swapping. If I then delete the solutions (in shared memory), I see the memory usage in 'gr_osview -a' go down! But I haven't accessed the solution data for a while and it should have been paged out. Any ideas about what's going on? Thanx.
