?I've had similar problems with tables before and the only thing that

?restarting it again at the top.  It seems that sometimes you can use

?at the end of the day and left for home and when I came in the
?next day to pick up my printout found out that the system administrator
?finally had to cancel my job 8 hours after I had left.  What had happened
?was the table went into an infinite loop and tied up a majority
?of our CPU processing time.  They weren't too happy with me that day.

From working with people that are serious troff/tbl hackers I can predict
that the bug most likely is in tbl, not in MM or troff. Tbl never checks
the distance to the next trap, so whenever a table hits a trap or end of
page the table gets messed up, since tbl generates code that does not print
the table completely from the top to the bottom. Trying to go up and down
on a page only works as long as you don't hit a trap.
