I have more news on this bug. It is possibly a bug with Hardy in general
and not with squid specifically.
I turned off squid and apache and let the machine just run (doing almost
nothing). The cache did not appear to grow much at all, definitely not
at the predictable rate it did when squid was turned on. However, after
16 hours the cache had grown to consume most of the memory even when not
much was really running. The activity of squid was probably just making
the memory problem happen more quickly.
This install of Hardy server is running on the most recently available
Mac mini hardware.
Here's the output of "free -m":
total used free shared buffers cached
Mem: 979 915 64 0 69 778
-/+ buffers/cache: 67 912
Swap: 2870 0 2870
Here's the output of "ps aux"
