Set the second server in set::defailt-server. The only problem with this, is very few clients actually support the redirect numeric.

This means exactly what it means. The IRCd is out of FDs for sockets, and unfortunately, when this happens it can't inform clients of the redirect-server because it can't fully open the connection (because this requires open several more sockets for the identd request and DNS lookup). All it can do is send that nice ERROR down to you and drop the connection. The solution? Set your class::maxclients to a value lower than 948 (which appears to be your max limit). Alternatively, up your ulimit -n if you have permission to do so, and recompile the IRCd with a higher MAXCONNECTIONS as documented in the FAQ.
