Hello, This topic has been discussed at least a couple of times in the past, but is there currently any way to make NSD ignore out-of-zone data or other errors in the zones or make NSD skip invalid zones? At least with NSD 3.2.16 or earlier any such errors cause NSD rebuild fail and thus prevent NSD from restarting. This is especially problematic in environments where NSD acts as a slave server for hundreds or thousands of zones. Because NSD needs to be restarted every time a zone is added or removed, any errors in a single zone make the whole restart procedure fail. Antti
