      @maitops yes, since 10 days. I also disabled hn ALTQ support (no clue if it's necessary). Observing kernel hvevents, no issues. But I have to wait 2-3 months to say, that it's stable.

        @maitops unfortunately, today morning we encountered network outages and the firewall needs to be restarted.

          @Bismarck said in pfSense 2.7.2 in Hyper-V freezing with no crash report after reboot:

          No hvevent storm here for 6 days and 23.5 hours since my last update,

          So this was setting the power management to 'high power' in Hyper-V? Which presumably disables throttling down the VM in some way.

            Yes, or just disabling the power management/green feature of the Nic should be enough, this is how it is right now on my Hyper-V host. There was a message (no error) in the Windows event logs about switching states or so, while the hvevent storm.

                Quick update:

                c941ae86-6ebb-40bb-a5e5-7ce0c05a60ce-image.png

                Had to reboot once because auf updates, but since than rock solid no incidence. Enabled all extra IP-Lists and Suricata and so again.

                @maitops Just disable all energy saving features of the nic or select high performance power profile in windows for a test.

                It must be the power state switching or the system tunables I did im my last update post.

                    Did you try the loader.conf.local and system tunables from the screenshot?

                      @Bismarck Yes, iI changed the loader.conf and rebooted.
                      the tunable, not everything, only:

                      hw.hvtimesync.sample_thresh
                      hw.hvtimesync.ignore_sync

                      i can try to set all the others too

                        You should set custom loader values in /boot/loader.conf.local (create that file) to prevent them being overwritten by the system.

                          is this the same underlying issue as

                          https://forum.netgate.com/topic/197248/pfsense-2-7-2-ram-leak-wired-memory-pool/11

                          might be irrelevant it is on a hypervisor.

                          solution looks like it might to update to pfsense 2.8.0
