I suppose this limit should be increased. It sounds like a ulimit problem (http://stackoverflow.com/questions/24955883/what-is-the-max-opened-files-limitation-on-linux), but could also be FDSETSIZE problem if irc server version is old and uses select() (http://man7.org/linux/man-pages/man2/select.2.html).
