      @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
