It sounds like your problem is that you have hit a critical point where
you have more processes actively running, that need to stay in RAM,
than you have RAM. Adding socks, or having your cache grow a little,
may have just "pushed it over the edge."

For example (simplifying a bit) if you have named, socks, and squid,
then everytime you get a squid request, squid will have to be pulled
off the swap and into RAM, forcing out named; then when squid does a
DNS lookup, the OS will have to pull named off the swap and into RAM,
forcing out socks; then when squid does an HTTP request, the OS will
have to pull socks off the swap and into RAM, forcing squid back out,
and so on.

The quickest way for now is to reduce the cache_mem setting in the
squid.conf file, but the problem is not so much Squid itself, as the
whole of the software running.
