A better solution would be a kernel patch that hooks into the SIGSEGV signal handler and logs all segmentation faults. A predefined list of programs can be monitored. Maybe it's fesable to log segfaults of all root processes.
Aren't seg faults logged already? I was kind of assuming that in my previous mail. My FreeBSD systems all log seg faults out of the box since the /etc/syslog.conf is logging at kern.debug (not sure what level seg faults are off the top of my head). Coulda sworn I had my Solaris boxen did this too, but a quick test shows otherwise. Hmmm... What systems out there can log seg faults and other memory errors from the kernel? Some people mentioned searching for core dumps, but you should not be having root owned processes dumping core anyway. -- Crist J.
