I got a box running SLES 11 SP2, we're running an old fashion application on which the clients telnet to the SLES Box. My problem is that the /dev/pts/ number keeps growing. It seems like if the lower channels are not being free when a client logs out from the system. If I log into the system with /dev/pts/83 and I log out from the system, when I try to log in again I will get another /dev/pts/ number even there's nobody else logged into the system in /dev/pts/83.
I got another box with more users, this one is running SLES 11 SP1 and it working fine.
