It didn't.

It's just a matter of how to read the amount of free memory in Linux.
It's not easy as the OS uses any free memory as buffer/cache for the
filesystem.

Under normal operation there should be around 5-12MB "free" memory, if
not there is something wrong..

You have 657 MB free. Plenty free memory there.

"free -t"

And Squid is using 168 MB.


So everything is just in order. It's just that Linux does not have a
simple "free memory" value. The best approximation is the "Free +/-
buffers/cache".
