You can set max_filedesc (or the actual name: max_filedescriptors) to
anything you like.
If the system limits are set to anything less Squid will downgrade to
those and display a warning. Unfortunatly this is done before cache.log is
opened so the warning usually appears in syslog and gets overlooked.

Thanks for the /etc/security/limits.conf hint.
