Every time we've seen a problem like that, it's turned out to be a 
faulty switch or a similar network-level problem, not a problem with 
memcached. Try testing for packet loss between your Web servers and your 
memcached servers when you see the problem happening.

If that's not it, you'll need to tell us a bit more. How many Web 
servers? How many memcached servers? How are they connected? (Network 
speed and topology.) Do you see the problem on all your memcached 
servers or just some of them? At all times of day or just during periods 
of peak load? What kind of hardware is everything running on? Which 
operating system? What's the CPU idle time on the machines in question?
