ll -R /dev/pty | wc -l
How many devices? You may need to bump up ntpy, nptys and nstrtel kernel settings and create additonal devices.

# cd /dev

# insf d pty s 1024 e v

# insf d ptm s 1024 e v

# insf -d telm s 1024 e v

# insf -d tels s 1024 e -v

Bharat ,

Check with :

# who -u | wc -l
( Are you running short of tty )

Then you need to increase the npty , nstrpty , kernel values , by default it will be 60. It defines system wide maximum numbers of stream-based pseudo ttys that are allowed in the system.

Cheers,
Raj.
