        if (!getrlimit(RLIMIT_FD_MAX, &limit))
            {
                if (limit.rlim_max < MAXCONNECTIONS)

                        (void)fprintf(stderr, "ircd fd table is too big\n");
                        (void)fprintf(stderr, "Hard Limit: %d IRC max: %d\n",
                                      (int) limit.rlim_max, MAXCONNECTIONS);
                        (void)fprintf(stderr,
                                      "Fix MAXCONNECTIONS and recompile.\n");
                        exit(-1);
                    }

So this is something you should either fix with setrlimit (ulimit), but
that doesn't seem to work for you. Check that it atleast is set like you
wanted.

Linux 2.2 shouldn't have a problem with more then 1024 connection, but for
2.0 you needed a patch ...

It could be that you need to change some headerfiles (and recompile
kernel?) before it really works.

I also suggest you make sure that you use poll() if you use linux 2.2.
(#define USE_POLL 1 in setup.h), but you probaly are already.
