Well, the one obvious difference is that cron as service runs from another
account (SYSTEM).  Another could be that the mount points and environment
are different inside the application.  Try adding "env > /tmp/env" and
"mount -m > /tmp/mounts" as one-time commands to your crontab and
comparing the output to that of the same commands run from a shell -- that
might provide some clues.  If all else fails, you could try to run cron
from a SYSTEM-owned shell and see if that makes a difference.  To get a
SYSTEM-owned shell, you could use the "at /interactive" trick (search the
archives for an example).
