[Pdns-users] Recursor problem?

Nov  9 04:02:01 boralis pdns[29822]: Recursive query for remote [IP REMOVED] 
with internal id 19 was not answered by backend within timeout, reusing id

I am getting a few of these errors popping up from time to time with the pdns 
2.9.19 package compiled from source. When I used the older 2.9.18 static RPM I 
never saw these. Any idea what might be causing them? The removed IP is my own 
IP address for the machine that pdns and the recursor both live on.
