Which a used box should only have very little free (about 1MB), or else
your OS is misbehaving. Some RAM is used for applications, other for OS
managed buffers which are automatically reclaimed if there is
applications demaning more memory.

So you are saying that you run out of SWAP, causing the box to crash?

Does not make sense.

If you only get 40MB back by stopping Squid, then Squid is only using
about 40MB + some.

See the cachemgr "General Runtime Information" for information about how
much memory Squid is using. If the "Free" value is high then you MAY
have a problem with malloc, and there COULD be a reason to try dlmalloc.
