"Total in use" is how much memory Squid has allocated.
"Total free" is "overhead" caused by your malloc package.
"Total accounted" is how much of the allocated memory Squid knows what
it is used for.

When "Total free" grows large then is it time to look for another malloc
package. This does not seem to be the case here so you do not need to
look for another malloc package.

When the difference between "Total accounted" and "Total in use" grows
large (or when when Total accounted grows huge), then is it time to look
for Squid bugs. So you and a couple of other who have reported similar
symptoms are most likely experiencing a Squid memory leakage causing
Squid allocate more and more memory over the time.

No known fixes at this time as far as I know, but keep an eye on the
Squid 2.2 bug list available on squid.nlanr.net.
