OK.

The basic info states that the server is up for about 10+ hours.
and passed in this period of time: 152054 request which is about
230-253 per minute.

The cache is holding more then 20k objects and maximizing it's ram
memory usage (less 0.6%).
Considering that you are using 128MB for ram storage the service
should be considered 128MB used as more then normal.
In the log it states that the accounted memory:
403163 KB which is about 390MB in usage.
390 -128 = 262
so the only issue is about 250-260 MB which are being used and not for
cache.
the basic usage of squid is about 3MB if i'm not wrong but there are
operational needs such as buffers and in transit stuff.
So 255 MB to think about..
500 FD which means about 300-350 connections doubles 64kb.
then it's about 13-14 MB for in transit stuff.
So there is about 241 MB which needs to be justified.

These are the basics.
