There seems to be some confusion over the way these squid processes operates.
In your trace: " root 14719 0.0 0.0 24796 1076 ? Ss 14:26 0:00 /usr/sbin/squid proxy 14721 2.2 0.2 40212 10352 ? Sl 14:26 0:00 (squid) " the process "/usr/sbin/squid" is a daemon supervisor. Ensuring worker "(squid)" process remains running and restarting it on failures. Adding upstart to manage this manager process is redundant. Using -N is the correct way to start squid up to version 3.1 without the supervisor/master process. 3.2+ with multiple workers will require changes in either upstart or squid to integrate them better, but the -N mode is still available meanwhile to disable the SMP support. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to squid in ubuntu. https://bugs.launchpad.net/bugs/573853 Title: Cannot control squid "Unknown instance" -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
