Make sure the Max connections (maximum FD's) is a decent number, 256 or
1024 usually.

You need to set Y lines to allow the proper number of users.  Without
explicit Y lines, it will use values that are #define'ed in config.h which
are very conservative.  example.conf will be your best source, but an
example is below:

Y:1:90::100:500000:3:10

The 1 is the class (used in I, O, C, N lines)
90 is the ping timing
The third field is unused
The 4th field is what you are interested in, it describes the maximum
 links permitted (per I line)
The 5th field is the maximum sendQ
6th and 7th are for "clone control", 6th on your server, 7th on the whole 
 network

Make sure that your I line specifies the Y line class you want
for example:

I:*@*::*@*::1

You will most likely want different Y line classes for each "class" of
client.  One for normal clients, one for opers, and a few for servers
seems to be the standard for small networks.

Good luck and read through example.conf.  It has much more information
than you realize.
