Can you please try your suggestion - for me it's not working.  I already
have what you describe and basically DNS stops working without huge
delays here.  I'm not sure if the delays are due to massive amounts of
logging generated due to endless retries or because the max number of
parallel queries kicks in and the retries are stalling further queries -
however, it's not workable...

Note as I said in my previous email, I need to point the server to some
fake address, eg

	server=/10.in-addr.arpa/127.0.0.2

Setting it to 127.0.0.1 seems to be ignored and the queries still go out upstream

Either it's an artifact of my dnsmasq version (very recent), or there isn't obviously a way to surpress these?  

Any ideas on how to suppress please?

Thanks

Ed W
