(Shame on me ..., I got the answer in my question ...)
The answer is to add the following line to your /etc/system file:
set pt_cnt = nnn
where nnn is the max number of pty's you want (128 or 256 by example).
The error message crops up because /dev/ptmx is a 'clone' device,
rlogin oopens /dev/ptmx and it clones itself and allocates a new pty,
when it runs out it can't open the 49th one (for exaple) bnecause that
device doesn't exist.
