I've successfully set up squid and it's working as is should. I'm using "Squidman" on OS X Server (underlying squid version is 3.1.12). However, I want to use squid to block certain porn sites, so I grabbed the Pornography-list from

This list, however, is quite large (~16MB). I use the list like this:

acl pr0n dstdomain "/Users/admin/Library/Preferences/squid-acl/sqbl-org-pr0n.txt"

followed by

http_access deny pr0n

This works as it should with small lists (~ < 1 MB), but if I want to use this list, squid is refusing to accept connections and acts like if the software would not run. If I comment the list out, everything is fine.

So, is there kind of a general limit in list-length or something similar? Is this problem known?

Thats odd, our blacklists work quite well with squid3.x, if you are using an older version of squid, you should upgrade to a modern version. Older versions of squid have severe performance issues with large acl lists.

Squid2.x is outdated crap.

Since the poster specifically mentioned Squid 3.1.12, this answer doesn't really help much. – Jenny D May 16 '13 at 7:21
