After several restarts I thought that there must be another behavior which causes the loop. I don't payed attention, that I had changed the login to using password. In this case the loop exists. Without password I had no loop with and without NTPDATE for several restarts.
But with the last restart I had a loop with login without password. I deinstalled NTPDATE and had no loop after restart. Strange behaviour. I give up as these things are to heavy for me. Adding syslog as attachement where you can see the time leaks. ** Attachment added: "syslog" https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/1015041/+attachment/3196081/+files/syslog -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/1015041 Title: Conflict between NTP and NTPDATE To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/1015041/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
