Default telnetd: open /dev/ptmx: No such device.

I used Solaris 2.5.1. Sometime when I telnet to my host, it has
messages below.
telnetd: open /dev/ptmx: No such device

At that time on console, I check "ls -ld /dev/ptmx" below.
lrwxrwxrwx 1 root root 30 Nov 13 2001 /dev/ptmx -> ../devices/ps
eudo/clone@0tmx

How can I solve this problem ?

Thank you very much.

You're out of pty's. Add the following line to /etc/system,
touch /reconfigure and reboot:

set pt_cnt=128

Type in "telnetd: open /dev/ptmx: No such device"
Click on "I'm feeling lucky"

Next time a little bit of research before posting please...
