It sounds like the 128MB you have in there is just barely enough for
the Squid process itself, and not for anything else, including the
kernel, so it's swapping. Here I'm using Henrik's rule of thumb of
Squid RAM = cache_mem + (8MB per GB cache) = 24+(8*13)=128MB. I'd try
sticking another 64MB in each machine as being the simplest solution.
