Hi,

A strange  problem reappeared today.  After  some time,  I can't launch any
command that use  /dev/[pt]ty8. Only this one  is affected but it of course
prevent any new tty to be open since /dev/ttyp8 appears free but no process
can attach to it. 

I have  icons to launch an  xterm that runs  Trn or Elm  and  each time the
window appears and disappears.  I've  tried to  ktrace  the xterm and   its
children but I don't understand why this fails. 

I  now have the following xterm  in background. It enables   me to open new
ptys but eats a lot of CPU... 

18477  p5  R      3:01.18 xterm -e sleep 10000000

It  has taken over /dev/ttyp8  but as soon  as the  sleep  ends, it will be
"free" again. pstat -t shows that

64 pty lines

Anyone with an idea about what's going on ? (Bruce ?)
