OK, yes all your mounts are system. Looking back over your original
comments, what doesn't work again? You seem to indicate that cron is
running. The output you show indicates it did run. But you claim it
didn't run a script. How did you determine that? Perhaps you're
interpreting the fact that you're having problems accessing the network
share as a cron script execution problem?

Good question. Using your example above,
//sons-clearcase/Views/<viewname>. That's what I'm assuming lacking any
other information from you.

Assuming you're trying to access your home directory in your script, yes.

>I had checked and read a lot about cron in the archives before this. I didn't see anything that explained it. I saw stuff saying that cron cannot access network drives. Does this also mean that cron cannot access network mount points say like when you mount /mnt/share //<server>/<share>? Does it main you cannot then run /mnt/share/myscript?
Yep, network drives are a no-no. If this is how you're trying to access
the network, then that's your problem. Try using the UNC paths directly.
If that doesn't work, I can only point you to the mail archives. I
remember this being discussed and my recollection is the solution was
'use UNC paths'. But my memory could be wrong. Perhaps someone else's
memory is clearer on this subject.

At the moment, no.
