Public bug reported:

The max_filedescriptors configuration directive is being ignored on
Trusty.

To reproduce the problem, set max_filedescriptors in squid.conf and run
the following command:

squid3 -k parse 2>&1|grep max_filedescriptors

The following output should result.

2014/11/06 15:21:15| WARNING: max_filedescriptors disabled. Operating
System setrlimit(RLIMIT_NOFILE) is missing.

Indeed, regardless of the max_filedescriptors value specified in
squid.conf, squid will run with a maximum of 65536 file descriptors
available. This can be verified with:

grep 'file descriptor' /var/log/squid3/cache.log
2014/11/06 15:30:45| With 65536 file descriptors available

The reason for this is that squid has been built with --with-
filedescriptors=65536

Rebuilding the package without  --with-filedescriptors, squid honors the
maximum number of open file descriptors set with ulimit.

Fedora also had a similar problem:
