Tell us more. If you can't start enough processes/threads to handle the number of incoming
connections, then 
setting keepalivetimeout from 15 to 5 seconds or turning off keepalive entirely will boost
the apparent number 
of 'concurrent' connections able to be handled by the server. I've found this useful in several
customer cases 
I've worked on.  The eventdriven patch should solve this problem quite handily.
