Is there a Memcached timeout value?

[Pavel Pragin]

Hello,

I have 3 apache web servers in a cluster that all run memchached on the standard port 11211. They are using the memcached php module to communicate with memchached on port 11211. I am seeing issue that the connection this port are not always terminated and just sit there. Eventually I get so many open connection on 11211 that memcache stop accepting new connections. How can I keep this from happening. Is there a timeout value I can set for memchached?

These are the 2 web servers:
192.168.1.49
192.168.1.51
192.168.1.52

Small sample of netstat output:
