Hi all,

Here's an unusual problem. I run my MBone router off a FreeBSD machine. Like on any machine
I take care of, I have this little script that runs from cron every minute that checks
if the service I want to keep running still runs. Here it is:

#!/bin/csh
if (`/bin/ps -ax | grep mrouted | /usr/bin/grep -v grep | /usr/bin/wc -l` < 1) then
   echo "Mrouted Died, Restarting" >/dev/console
   sleep 30
   /usr/sbin/mrouted
else
   echo -n "." >/dev/console
endif

Sometimes (very occasionally, like once every 2-3 months), I get this piece of mail:


X-Cron-Env: <SHELL=/bin/sh>
X-Cron-Env: <HOME=/root>
X-Cron-Env: <PATH=/usr/bin:/bin>
X-Cron-Env: <LOGNAME=root>
X-Cron-Env: <USER=root>

/usr/bin/wc: Permission denied.


What could make it so wc becomes non-executable for root??

TIA,
Yves Lepage
