[Pdns-users] [dnsdist] Marking downstream Unexplained

[Alejandro Adroher Mellado]

Hi all, 

Currently I have 3 dnsdist server (one as abuse pool) and I'm planning to introduce 3 more instances.

Sometimes, maybe randomly I got the connection between servers down and up again always I one second. I have the servers monitored  with opennms and I have no news about any issue on servers or networks. But I still getting sometimes the next system event.
