Sorry, one more.

After making the change I now do get the pings graphed. However I am 
also continuing to get the same errors in the logs:

Is it possible that "send_only 1" is being ignored in 
regular_testing.conf, and so in the absence of "receive_only 1" it is 
trying to do tests in both directions?
