This would indicate that it might have to do then with prolonged exposure to memory and the memory-system(s) (swap, paging). Is there anyway to monitor the syscalls and the amount of memory used and released by each call Matt?

Yer kidding right? A program that _needs_ 100 MB or more? Surely yer kidding... I haven't seen a program in normal corporate/home use that justifies the memory usage of 100 MB or more including NetScape's Navigator/Communicator. > 2) I have never seen a system crash as such.

I wonder if X could be the originator of the problems, my guess is it can't since Linux uses the same X and I haven't heard any complaints from that corner. Also it's nice that the program dumps core, but afaik without debug symbols it's not much use. --- Jeroen Ruigrok van der Werven It's a Dance of Energy, asmodai(at)wxs.nl when the Mind goes Binary...
