Apps crashing

[Rick Leir]

This morning, the desktop has frozen twice (can still ping the box).  A 
reboot was needed both times.  Should I repost to devel or test?  I need 
to know whether to look for hw or sw problems.  I could enable core dumps 
using ulimit, but would I find the problem by poking through core dumps?
Where can I add 'ulimit -c 1000000' so it will affect all exe's, maybe in 
rc.local?
cheers -- Rick
