You have run out of ptys (pseudo terminals).  You can increase this with
the following line in your kernel configuration file:

	 pseudo-device pty  NN

replacing NN with some number, usually a multiple of 32.  Rebuild the
kernel, and you'll have that many ptys available.  I believe the absolute
maximum you can have is 256.  You need one pty for every telnet session.
Other programs (such as emacs) can also use ptys.  So be sure you have
enough for your maximum needed number of logins, plus some slack.

You will also need to make sure you make the appropriate files in /dev.
Use "MAKEDEV ptyN", where "N" is "0" through "7", to make the following
device nodes in sets of 32:

	pty0:	/dev/ttyp[0-v], /dev/ptyp[0-v]
	pty1:	/dev/ttyq[0-v], /dev/ptyq[0-v]
	pty2:	/dev/ttyr[0-v], /dev/ptyr[0-v]
	pty3:	/dev/ttys[0-v], /dev/ptys[0-v]
	pty4:	/dev/ttyP[0-v], /dev/ptyP[0-v]
	pty5:	/dev/ttyQ[0-v], /dev/ptyQ[0-v]
	pty6:	/dev/ttyR[0-v], /dev/ptyR[0-v]
	pty7:	/dev/ttyS[0-v], /dev/ptyS[0-v]


For example, if you specify 128 ptys in the kernel, be sure you have
the device nodes made for pty0 through pty3.

> fyi: kernel compile with MAXUSER 256

That should be more than enough.
