Greetings...

	I have an extremely puzzling problem on my System V Release 2
system (Microport).  In the past few weeks, I have noticed that my cron 
log file contains many entries which look like this:

>  CMD: /usr/lib/uucp/uusub -celevia
>  uucp 110 c Wed Oct 28 06:37:06 1987
<  uucp 110 c Wed Oct 28 06:37:07 1987
>  CMD: /usr/lib/uucp/uusub -celevia
>  uucp 112 c Wed Oct 28 06:38:35 1987
<  uucp 112 c Wed Oct 28 06:38:37 1987

	Somehow, it seems that cron gets confused and starts executing every
command *twice* -- this has a pretty devastating effect with some commands!
I have checked and re-checked: the commands appear only *once* in the
crontab command files (crontab -l) and I have only one incarnation of
cron running!

				I thank you all in advance...
