You either have too few pty's defined (and need to rebuild your kernel and run MAKEDEV), *or* you are being hit by a denial-of-service. To test the second case, restart inetd with a "-R 4000" and see if it helps the problem (inetd suts down daemons that respawn more than this number of times in a set time period -- see "man inted" for details).
