It seems to me that it is not a good idea to do load testing on some 
third-party server.

An error condition can trigger such an error.  It isn't related to 
the BIND configuration file.

There is a long thread at 
https://lists.isc.org/pipermail/bind-users/2011-June/084405.html  The 
question might be what is the maximum QPS handled on hardware similar 
to the one you used for the test.
