Memcached problem with maximum connections

[Dharmesh Maniar]

There are around 40 local web servers.
I am using Apache with php. 
Apache is running as worker.
Here are the apache parameters:
StartServers         10
MaxClients         1200
MinSpareThreads     25
MaxSpareThreads     128
ThreadsPerChild     30
ServerLimit         40
MaxRequestsPerChild  10000

These parameters are same on local servers as well as servers on the other
network.

Regards,
Dharmesh.

How many web servers are local?  What web server / sapi is in use?  If 
Apache, what is the StartServers, MinSpare, MaxSpare and MaxClients.  If 
it is fastcgi, how many children are allowed per server?
