Hi Marc, Such messages tell it has been detected some issues with NetFlow datagram sequence numbers. This can be caused by packet loss between an agent and the collector, mistakes in the sequencing encoding among the others. Besides the warning messages, which can be turned off, NetFlow datagrams reaching pmacct are processed as usual.
Do you see such messages appearing regularly or occasionally? Can you spot a pattern (ie. only a subset of the devices are affected, jumps repeat the same way, etc.)?
