      Hi!

      Since upgrade from 2.4.3 to 2.4.4 Iโ€˜ve noticed some random latency spikes on both WAN interfaces. The latency on ALL gateways goes up to 100ms, even the LAN_DHCP gateway.

      Also ping graph from think broadband shows this issue:

      2.4.3

      2.4.4

      The other WAN is the same. Any hints?

        Is this something you can predict?

        Maybe sit watching top -aSH and try to see what is happening at the time of the spike.

          @jimp said in Since 2.4.4 random latency spikes:

          top -aSH

          This could be hard because it's only a few seconds (5-10s). It feels like the system hangs, but the GUI is working flawless.

            Anything in any of your logs around the time of the spikes? The main system log, gateway log, and DHCP log especially.

              Nothing in gateway logs.

                DHCP renew on the interface could explain the appearance of a momentary glitch

                  Might be possible! I have the problem that my Philips Hue bridge is crashing if Avahi is beeing used. This could explain that this glitch gets triggered.
                  I have to setup the bridge to the same interface as my LAN that it works. Unfortunately Avahi only works 80% and let the bridge crash.

                    There is a rewrite of Avahi coming, it's on 2.4.5 snapshots right now for testing. It might help.

                      Maybe I give it a try. Can you recommand the snapshot release right now for beeing "stable"?

                        The latest one is generally the most stable but they are still snapshots. We don't test them all individually before they go up, so there could be problems there.
