The answer is simple...

I was running out of Pseudo Terminals which are in /dev/pts/
that are by default only 48 in Solaris 2.5.1 and
maximum to set 3000..

how do you add more Pseudo Teminals??

you add the lines..... (in your /etc/system file)

set pt_cnt=1024
set npty=1024

if you want 1024 Pseudo Terminals..

and do a nice "boot -r"

I appologize for this question since is appears in the Solaris2 FAQ
under these items..

5.27) I get /dev/ptmx: No such device when attempting to telnet/rlogin
in.
    You need to increase the number of pseudo ttys (See 3.39).

3.39) How can I have more than 48 pseudo-ttys?

Thanks..
