I have had a similar experience with csh programming (Ultrix 3.0).  I have the
identical program running on 2 microvaxes (1 BA23 1 BA123) that are supposed
to do a logout of idle users.  When run from cron, the one on the BA123 (9MB
RAM) works fine,  the one on the BA23 (6 MB RAM. not sure if mem is
significant) will not work.  It stops partway through.  However if i run it
as root (su) it works fine and if I kill cron and restart it as root, it
works fine.  I posted this once before and got no real answers but this
problem sounds similar enough that I thought I'd mention it again.

Any Ideas
