Distributed Network Syncing

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,
