Hi Mike,

I don't understand what this means.

Why would core files from area2png be dumped into /var/core?  Also, why
would the core files be owned by 'root':

/var/core% ls -alt
total 14260
drwxr-xr-x   2 root     other        512 Nov 20 07:12 .

drwxr-xr-x  38 root     sys         1024 Nov 19 10:13 ..

Also, I am suprised by the differing sizes of the core files and also
the fact that there are two entries for pqinsert!?

I did notice a core file from area2png yesterday morning (in ~ldm), but
I didn't worry since it did not reappear after it was deleted.  Also, I
don't see any gaps in the images that are being compressed by area2png
and inserted into the LDM queue, so I am not certain why the there would
be core files at all.
