  I had the same problems; which I eventually diagnosed as a memory leak.

  My system had a cron job running every minute (date>/tmp/date) just to
  make sure things were working, plus a uucp which cranked up about three
  times a day.

  After about two days, no job would be able to run (out of memory, 
  "Try again later.") - thus leading me to conclude the memory leak.

  This was present in 1.3, and 1.4a, on an XT clone.  I spent a little
  time trying to find the leak, but eventually gave up, and simply
  rebooted every morning.

  At the time, I posted a similar message describing the problem; but
  got no answer.  At this time, due to a move, my minix machine is down;
  so, I haven't researched or even upgraded to 1.5.10 (I am hoping the
  upgrade will remove the problem.)
