Some people are seeing huge numbers of filterdns processes. For instance:

http://forum.pfsense.org/index.php/topic,57143.0.html

on the filter's instance of filterdns. Not seeing that on one of our systems, but another has 3 instances running. It doesn't appear to be happening because of the filter reload process. On the system where I'm seeing 3 instances:

[2.1-BETA1][root@fw1.hq.pfsense.org]/root(5): cat /tmp/filterdns.pid 
56384

That part at least is killing off the instance it knows about via its PID file, and re-launching it correctly. Something else is somehow duplicating instances of the process.
