>conclude that there is no such option, correct? Well, it depends on the reason for the timeouts. If the packet is getting lost along the way due to network issues, it would never hit the server, and you wouldn't have any logs of it. You could use filters on tcpdump (tcpdump -tt host x.y.z.a && port 53)and setup a script on a remote host to send a stream of queries. You don't necessarily have to capture all traffic to troubleshoot the problem. Make sure your servers are time sync'd properly so you can correlate the logs. Otherwise, if the issue is happening after the packet reaches the server, then I'd bump up the debug level and turn on a bunch of logging and make sure ntp is working fine and start watching logs while generating a bunch of traffic from a test box.
