I took a look with "free -m" and the situation looked entirely different. Also, I found the true cause of that one system crash and it had nothing to do with memory. My program was going through the scipts in /etc/init.d and doing a "status" on them to see what processes were up. It turns out that in openSUSE 11.4, that directory contains a script called boot which isn't a startup script at all, but the first script run at system startup, which does a lot of very basic things like mounting file systems. So, when my program gave the command:
service boot status
it was simply ignoring the command line argument "status" and executing, causing my program to stop and often causing a crash of my whole virtual environment. It had nothing to do with running out of resources.
Thanks again, Corona.
