pfSense 2.7.2 in Hyper-V freezing with no crash report after reboot
-
@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:
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.
-
@Bismarck I still have the issue, I have a mellanox connectx-6 Lx NIC, I just disabled the "Interupt Moderation" too
-
I have a Intel 82599 and X550-AT2 in use.
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_synci 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
-
@stephenw10 My bad, i'm trying with this.
I will tell you if it solved my issue.
