Yes.

man 5 login.conf

You probably compiled it with fd's == 256 or similar, but this
is no longer a hard-coded variable. To immediately rectify the
problem - assuming you haven't already done so, install login.conf
from /usr/src/etc and edit the "default" entry "openfiles=64" or
"openfiles=256" (or whatever value you compiled into ircd).

As soon as limits(1) is committed (probably tomorrow), you should
probably restore openfiles=64, and instead create a class which
has the appropriate number of filehandles instead. Then, as root
in your rc.d script, put:

eval `limits -e -C class`

or don't worry about the class and use the shell independant:

eval `limits -e -n 256`

or assuming it is started from a /bin/sh script:

ulimit -n 256

Actually, if your process starts out as root, you can do the
last one now without having to edit /etc/login.conf at all.
