All the responses were the same. Here is one for your perusal (from
Pty is pseudo terminal Driver.It's created when you logon into system
via network or by some other method.It must be reaching the limits on
your system on your second attempt some of the PTY's must have freed up.
You may have to increase the Number of PTY on your system.You can do
that by adding a line in /etc/system file
set pts_count=128 (Default is 48).
You can check the pts on your system by giving command:
ls -1 /dev/pts* | wc -l
