XENIX 2.3.2 and cron

[Phil Hughes]

On a XENIX 386 Release 2.3.2 system we have a situation where
the cron process is started but it never executes.  If you kill it
and start another one, all is well.

I remember a discussion of this some time ago but as I remember the
case was that if there was nothing to schedule for a long time it
would never run.  We have stuff scheduled at least every half hour.

Any ideas?
