10.7: Manage firewall logs Network
After upgrading to 10.7 my firewall logs were filled with endless "Firewall: Allow foo connecting from to port 1234 proto=x". Happily the logging system can be told to selectively ignore these messages.

Certain applications use lots of incoming network connections, and the default behaviour in Lion when the firewall is enabled is to log every single allowed connection.

A single rule line in /etc/asl.conf can silence these useless messages.

? [= Sender Firewall] [A= Message Allow foo] ignore

You can add this line using your favorite text editor, but you'll need one that can save files with root-level permissions (like the non-App Store version of TextWrangler).

[crarko adds: I haven't tested this one. To be honest, I don't run the OS X firewall.]
