default max connection is 1024.

with mod_perl you can have up to # of servers * # of apache 
threads/children simultaneous connections, so it's likely adding more 
servers bumped you over the 1024 connection limit.

when i try to telnet directly to a memcached with max connections, i get 
an instant "Connection closed by remote", it doesn't hang around and 
timeout.
