User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3)

Description of problem:
There seems to be either a shortage of ttys or somehow ssh/xterms are
not able to open the next tty. 

Opening a new xterm or ssh session after the first couple results in
disconnection or the following message: 

Warning: no access to tty (Bad file descriptor).
                                                Thus no job control in
this shell.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Open four ssh or xterms
2.Try to open a 5th session


Actual Results:  Warning: no access to tty (Bad file descriptor).
                                                Thus no job control in
this shell.

And you are hung. 
I have tried it both locally and remotely.

Expected Results:  You should get a shell prompt

What kernel? Are you using udev?
Comment 2 Aram Mirzadeh 2004-09-23 07:54:21 EDT

Linux tigger 2.6.7-1.478smp #1 SMP Thu Jul 8 15:17:25 EDT 2004 i686
i686 i386 GNU/Linux

I just downloaded 2.6.8-1.541 and am going to give it a try.

udev is installed and USE_UDEV is set to yes, however I have not made
any changes to it from the test3 release.

Is this xterm, gnome-terminal or konsole you are seeing this error
with? Please also specify the exact rpm version number you use.

It isn't limited to local X11 sessions.  SSH from external sources end
up with the same error.

Using 'telnet localhost' will result in: 

Trying ...
Connected to localhost.
Escape chracter is '^]'.
telnetd: All network ports in use.
Connection closed  by foreign host.

# ssh localhost 
awm@localhost's password: 
Warning: no access to tty (Bad file descriptor). 
                                                 Thus no job control
in this shell.

And hangs the session.
Comment 5 Aram Mirzadeh 2004-09-26 17:24:55 EDT
More notes, this must be a 'leak' of some type.  After a reboot I can
open 30+ sessions just via xterm, after the system has been up for a
while ( in this case 3 days 9 hours ) I can only open more sessions if
I  close out some of the old ones.
