Sometimes (only happens periodically) when I run login from an xterm I get a 
message 
Terminal Control information suddenly vanished
Wait for login exit ...
but I still log in and the ownership of the tty file doesn't change.  I usually 
get the "not owner" message on the tty as well.  Below is an example.  A while 
back I ran out of pty's so I created additional dev files and up'ed the rpty 
entry in the kernel config. What's happening here?
The system is a dual proc 2100 running V3.2a.  I have 512 rpty's created and 
configured in the kernel.  My apologies if this is in the archive, I don't have 
access.
thanks, 
dan
