- I have had a number of problems with X freezing when pushed too hard.
- I have 16M ram + 16M swap and have experienced lockups when swap approachs
- 0k. This is usually a result of running too many xloadimage's at once. I
- have tried leaving the system to sort out it's problems but after about
- an hour of no disk activity or screen movement I reset it. I've experimented
- a bit and have noticed that I can get down to 20-30k swap free and things
- still run fine (haven't tried to get closer to 0k than that) but once swap
- is overcommitted, things tend to hang. I suspect that the last app started
- in a low memory situation like this should fail due to out of mem or related
- problem (malloc = NULL) but I have never seen an app die in this situation.
-
- Another symptom that someone posted earlier is that swapping will eventually
- stop and the screen won't update but moving the mouse (serial mouse) will
- cause more disk activity for a short period of time and then everything locks
- up solid.
