I don't have any 'at' jobs (that I know of).

I ran atq as myself as well as root an nothing showed up.  So now I'm
wondering what can possible create an at job on the fly.

Maybe I'll have to kick off a cron job to run atq until I can figure out
the culprit.

Looked there; directory is empty.

Thanks for the excellent suggestions.
