I was wondering if someone could help me with OpenSUSE's sysconfig editor in Yast. I was looking at limits (ulimit stuff mostly) and while I know how to find the amount of resident and virtual memory an application is using, I honestly don't know how to find some of the other items, i.e. how much is being used by a program, to tune the settings. I tried setting all the percentages to 50% hard limit and 33% soft limit (AMD dual turion laptop with 3GB ram and 6GB swap) but upon reboot, firefox would not run, and I could not figure out what limit it ran up against from a strace. I tried googling and the ps man page but I ran out of free time.

If someone could help me find the other info (data segment, stack descriptors, etc) on it while it's running, I'd greatly appreciate it. Thanks!

Opensuse 11.4 ??? or 11.3 or 11.2 or the old 11.1 ?
have you looked at the docs ?

Where did you set it in sysconfig to 50%? I cannot find such an entry in YaST, it’s just the file /etc/security/limits.conf I thought.
