Re: TFTP spawn issue

[Johnny Billquist <bqt%softjar.se@localhost>]

I think that is bad advice. If the max spawn rate is exceeded, there is
something wrong. Increasing the max spawn rate will not solve that, but
can cause greater problems. However, I suspect the end result will just
be the same, but it will have forked more times before disabling the
service.

What I'd do is I'd disable the service in inetd.conf, and run it by hand
on the command line, with debugging enabled. That would probably give a
hint on what the problem is.
