Bind 9.30 recursive quota error?

[snort]

I just upgraded my dns servers to 9.3.0 in the last week or so. Seems to be working ok but I'm noticing a strange new error in my system logs that I'm not sure if I should be worried about or not. 

   client 10.0.12.149 no more recursive clients: quota reached: 2 Time(s)
   client 10.0.12.150 no more recursive clients: quota reached: 2 Time(s)
   client 10.0.12.169 no more recursive clients: quota reached: 1 Time(s)
   client 10.0.17.12 no more recursive clients: quota reached: 5 Time(s)
   client 10.0.17.40 no more recursive clients: quota reached: 4 Time(s)
   client 10.0.17.41 no more recursive clients: quota reached: 2 Time(s)
