I have the same problem, tough I don't remove my squid servers very often.
I've partially resolved this problem thanks to the implementation of
the algorithm of my load balancer.
What it does, it's calculate the hash taking into account all the
squids in the pool, whether they're up or down. Then
I dealt with the same problem using a load balancer in front of the
cache farm, using a URL-HASH algorithm to send the same url to the
same cache every time. It works great, and also increases the hit
ratio a lot.

Actually, it is my case.
The URL-hash is helpful to reduce the duplicated
objects. However, once adding/removing squid server,
load balancer needs to re-calculate the hash of URL
which cause lot of TCP_MISS in squid server at the
inital stage.

At this moment, I have several squid servers for http
caching. Many duplicated objects have been found in
different servers. I would minimize to data storage
by installing a large centralized storage and the
squid servers mount to the storage as data disk.
