FreeBSD 2.2.*
/usr/src/sys/sys/types.h
---------
/*
* Select uses bit masks of file descriptors in longs. These macros
* manipulate such bit fields (the filesystem macros use chars).
* FD_SETSIZE may be defined by the user, but the default here should
* be enough for most uses.
*/
#ifndef FD_SETSIZE
#define FD_SETSIZE 256
#endif
---------
change this to 1024 (or 2048) and ircd will work fine :) (tested on ircd
with >800 users)
p.s.
FreeBSD 3.* -> #define FD_SETSIZE 1024
