AMD 10.0 - cron & atrun

[Jim Pazarena]

I've recently installed FBSD 10.0 AMD on an HP rack server.
A "ps" shows 574 cron instances running, and 573 atrun instances 
running.
But no actual jobs other than 5 or 6 running.
I 'think' the cron is open because it has triggered atrun.
But I cannot for the life of me figure out why atrun isn't terminating.
I tried an "atrun" at the command line, and it sits there, as "if" it
was running something.

Advice much appreciated.
