Delay in zone update after nsd-control write!

NSD

With NSD4, after "nsd-control write" the zones do not updates till temporary files have been moved or copied. It might not be noticeable with small zones.

Thanks.

Hi Kabindra,

For large zones the write can take some time. The nsd-control write
command spawns the reload-worker process to perform the write itself
(while the daemon continues to answer queries). And because the write
takes time, the other zone updates wait until the write is done before
the reload-worker process is available to process the other zone updates.

So, the other zone updates are then delayed until the write to file is
done. The zone may be big, but that write would not take more than a
minute or so? Is a minute delay before a zone update is processed a
problem for you? Or is there some sort of other delay happening (a bug) ?

Best regards, Wouter
