   Yes. First, find out about the thread and port usage:

   ps -F hurd-long -x -a

   Pipe the whole thing into a file for us.

   Then, "portinfo PID | wc -l" shows the number of open ports, where PID is
   the pid of pflocal.

   Then, find out what all those threads do:

   gdb pflocal
   set noninvasive on
   attach PID
   info threads

   (again, PID being the pid of pflocal)

   Is some thread stuck in some function? Are many threads stuck in the same

Good suggestions.  But before you do this, you might want to freeze
the process by making it crash.  `kill -ABRT PID' should do the job
provided that the crash server has been set up right.  Try `showtrans
/servers/crash' to see if it is, and use `settrans /servers/crash
/hurd/crash OPTIONS' to set it to do something sensible.  I'm not sure
what is the default, and you might want to make sure that orphaned
processes are suspended.  Try `/hurd/crash --help' to see what your
options are.
