For 10GB of cache and "cache_mem 8MB", the squid process takes nearly
120MB on my configuration (Linux, Squid 2.3.STABLE4, 256 MB).

In-memory cache indexes are pretty huge and proportionnal to the number
of objects in your cache (quite proportionnal to the size of the cache).

See : http://www.squid-cache.org/Doc/FAQ/FAQ-8.html#ss8.1

In your case (15GB of cache, "cache_mem 32MB" and 128MB of RAM) you
might have too much disk space allocated to your cache.
If the memory fills up early (when your cache_dir is nearly empty), then
it might be a memory leak.

Hope this helps.
