The last one would explain why sometimes the commands seem to
be "cut in the middle"; due to the complexity of the rlogin
stuff, it is well possible that on successive invocations,
always a different amount of output is produced. OTOH, the man
pages for cron don't mention such a restriction.
Any ideas on this?
No clue. I would definitely try 'strace -f -o /tmp/mybug.tra myjob' in
the crontab entry.
This way you'll know what exactly is the killer (a signal or a silent
exit after an error).
