Clients have no idea what your memcached servers max connections is. 
For example, we have 5 application servers that have a maximum of 256 
instances per server.  That means EACH memcached server must be able to 
accept 1,280 connections.  So, if you are running out of connections, I 
would look at what is connecting to memcached and most likely up your 
conneciton limit.  Ours are set to 4,096 just for good measure.
