Distributed Network Syncing

Hello,
I am running 3 load balanced Gentoo web servers and on each server
running a copy of the php library of memcache. I have setup memcache to
be distributed across all three webservers and under most cases this is
working fine. However, if for some reason, a web server falls out, when
I bring it back up some entries in memcache seem to either be empty or
have bad data. This bad data seems to propogate across the network
until I have to bring all 3 memcache servers down, then start one, hit
the correct webpages to prime my data, and then start the other two
memcache servers back up.
My question is: How does memcache sync data entries in a distributed
network? Is there something that I need to do to resync the servers
correctly when one has gone down.
I appreciate any help,
Jesse
