      I upgraded pfSense from 2.0.1 to 2.0.2 and now I'm seeing a flood of these messages in system log:

      dnsmasq[42227]: failed to send packet: Invalid argument

      Seems that DNS resolution for clients on LAN is still working, but something must be wrong…

      I looked at filter logs and don't see any port 53 traffic blocked by the filter.

      My DNS forwarder setup is rather simple. I have only checkbox "Enable DNS forwarder" checked and the external hostname of pfSense machine listed under "Host overrides"
