Public bug reported:
As far as I can see, upstart configuration file for squid3 tries to
raise limit of open file descriptors to 65535 in pre-start script.
Apparently, this is not working as expected, because squid3 starts and
reports 'With 1024 file descriptors available' in cache.log
Moving ulimit -n 65535 to script section that starts squid itself solves
this. Patch to /etc/init/squid3.conf:
--- squid3.conf 2012-04-20 17:37:12.636701094 +0500
