I wonder if something (PAM module, maybe?) is opening a
file on each connection and you're running out of per-process
file descriptors.
A similar thing happened here - although it wasn't sshd at fault. Len

It sounds like you've got the ones I would think of. A quick skim of

One possibility might be running out of pseudo-terminals to support

I have a problem, and I am unable to find previous discussions of it.
Any pointers or clues would be much appreciated.
