   Sounds like you're running out of process table entries to me.  Try
   increasing 'maxusers' in your kernel config (A good idea for X users
   anyway).  You may also want to make sure that you have enough ptys.

I really don't think that is the problem.  My `maxusers' value and
number of ptys have been the same for months, and this problem only
started a week ago.  My recent X usage has been much less exhaustive
than I have done regularly in the past.
