There is another very old bug (certainly present in System III already)
that sometimes a process which is swapped out while waiting for an alarm
never gets swapped in again. I know it may seem strange, but we really had
cron become ineffective that way on an old System III system. So you may
want to make sure cron is not swapped out. (in that case killing and restarting
helps too)

I haven't experienced it on my 286-Xenix system yet since it never swaps.
(i bought lots of memory when it was cheap)

Paul.
