ENOBUFS error in network programs -- how to fix?

[Bob Weissman]

Lately, on a Vax 11/750 running 4.2bsd, we've been getting ENOBUFS
errors ("No buffer space available") when users attempt to connect
to another Ethernet site via rlogin, rsh, etc.

I've been unable to track down the source of this error, and have
found that rebooting the Vax makes thinks OK again for a couple of
days.  None of our other hosts have this problem.

I'd like to find a more gentle way to fix this problem.  Can
anyone help?

Thanks,
