Amos said something? Got no mail from him.

Sure, maybe some FTP files are not to be cached.

I do not want to cache any. And I think a 'cache deny all' does that.
Nevertheless, even with no caching at all the Squid process constantly
needs more memory and squidclient reports that the memory is used for
the 2K buffers.

Just try it. Squid with default configuration and cache deny all and
then do some wget ftp://server/path/. Each requests will increase the 2K
buffers.
