To determine how much memory the dnsserver processes uses, use your
favorite process statistics tool (ps, top or whatever). They should not
grow much once being used for a while.

First question is if you have told Squid to release unused memory? See
memory_pools and memory_pools_limit in squid.conf.

Second, most memory management routines (malloc) for UNIX processes
never release memory once allocated from the OS.
