Guys,

We are seeing tons of these messages reported;

Memcache::get(): Server 10.3.230.15 (tcp 11211) failed with:
Connection timed out (110)

They are reported on all six of our webservers. Memcache is working
but lots of connections are timing out as reported with the above
messages.

We are running memcached 1.2.5 with php-pecl-memcache-2.2.3 (we also
tried with memcache 1.4.5 but had the same errors). We have PHP 5.2.6
running on x86 Hardware with Red Hat 5.5.

We have six web servers all running Apache 2.2 on prefork mode.
Prefork MaxClients is set to 192.

Our memcached config looks like this;

PORT="11211"
USER="memcached"
MAXCONN="2048"
CACHESIZE="2048"
OPTIONS=""

We are running memcache between webservers on a LAN, no Firewall or
iptables being used.

Memcache is used to cache output of scripts most of the time. It could
be HTML or XML that is delivered to client.

Our tcp values look like this;

tcp_fin_timeout
60
tcp_max_orphans
65536
tcp_orphan_retries
0
tcp_keepalive_probes
9
tcp_keepalive_time
7200

I am totally out of ideas, I can't see any dropped packets on the
network, I just don't know what else to check.

Any ideas as I am pulling my hair out!

Thanks
