[BLUG] Fwd: possible causes of segfaults

Hiya,

I just installed a new file / computation server at my work, and a few
days into its tenure, I've started noticing some segfaults.

For instance, I was running a bunch of image processing jobs, and
ImageMagick's "convert" program segfaulted.  I ran it again on the
same data, and it did fine.  So I'm wondering if I have bad hardware,
or bad libraries, or what?

Possible causes of segmentation faults that I know of:
Hardware --- could be very random and difficult to find, might need to
totally shut down the server and run a memory tester for days in order
to find.

Filesystem corruption --- should be reproducible, right?  if "convert"
segfaults once, it should do it again...

Libraries / os problems --- should be reproducible too, right?

Any advice?
