Dear all, Thanks for your detailed reply.
@Charles, if I unplug my 1-Gbit internet line then about 250 user are not happy. An my supervisor too. But I know how to simulate this. It happened on an internal ntp server with version 4.2.8p1 with a peer connection to another internal and 2 configured upstream server to the DMZ ( also internal ) But I have seen this behavior on this 2 ntp server at the DMZ too. Of course I didn't look at the source code. And obviously I will not understand it. @Brian, I read 3 times your information and tried to follow. Definitely I looked not only once after the change. SO it was not only between request and reply. What I take with me: yes it can happen, it's a normal behavior. Thanks for your advice.
