Help! Network timeout (0) error
August 29, 2010 07:40AM
Hello,

I use memcached (v1.4.4) extensively and we've started suffering from
the following error:

MemcachePool::get(): Server localhost (tcp 11211, udp 0) failed with:
Network timeout (0)

This is a PHP error. We use the php-memcache module (v.3.0.1 I think).
After digging through the source code from both the php module and
memcached itself I am unsure who is generating this error, but I'd
thought I'd ask here anyway. It happens maybe 5% of the time. The only
half-useful piece of information I've found about this:
http://www.oscarm.org/2008/8/troubleshooting-connection-problems-memcached
- but I don't use iptables, I use ufw. So I don't think it's
relevant.

I'm wondering if this is a configuration issue on my memcache server's
part - since in the last few weeks our network traffic has increased.
We run 3 different instances of memcached processes on the same
server, all of which are being connected to by a load balanced array
of webservers.

Any help, insight or ideas would be very appreciated!
