Has anyone noticed duplicate cron jobs being run? It doesn't happen all
the time, so it may not have been noticed by me until I installed mrtg
(which runs a root cron job every 5 minutes). At first, I thought it was a
bug with mrtg, since the error email complained that the mrtg lockfile
already existed, but everything seemed to be working anyway. I then added
MAILTO="devnull" (where devnull is a bit-bucket alias). Oddly, I still
seem to get messages from root, despite the fact that the MAILTO line says
not to send to root! It's almost like crond is running a second instance
at the same time, but screwing up some of the info (like the MAILTO
line). I am running mandrake 6.1.
