Squid and snort stopped after pfsense upgrade from 2.0.3 to 2.1.5
I upgraded my pfsense from 2.0.3 to 2.1.5. It runs smoothly but after 3 days, my WEB GUI hangs and as I check the CLI error says readdir() expects parameter 1 to be resource, boolean given in /usr/pkg/squid.inc. Then I rebooted the machine, my WEB GUI started by squid and snort does not starting.
You have reinstalled the packages after the upgrade?
Sometimes removing them and reinstalling them solves issues that merely reinstalling them (without removing them) does not.
