PFSense 2.4.4 not responding at console and web interface CRITICAL BUG! HELP!

That's correct. It will apply via the GUI like that but it's then permanent. If you test it from the CLI first and it does something unexpected you can just reboot.

Hi Stepen yesterday error is gone and server work stable access to cli and web UI was anytime when was small trafic but after night when trafic was zero error come back again. Need more time to watch on the actions and need to tweak to max performance or maybe I can add some cron jobs to prevent falling asleep webconfigurator or this is more fundamental timecounter problems?

kern.timecounter.hardware is still set to ACPI-fast?

You could try the TSC-low timecounter also if you#re still seeing issues. That is lower quality though.

@stephenw10 said in PFSense 2.4.4 not responding at console and web interface CRITICAL BUG! HELP!:

That is lower quality though.

Last hours work stable :) Thank you for the professional help from expert its helps for my case!
Fought this problem for several months, there was no desire to leave PfSense.
This is my first experience with BSD systems. Several years watched pfsense and not in vain awesome project

What you mean That is lower quality though?
I have enother qestion about VM cputime (units) what optimal recomended value for PFsense in KVM?

Does it make sense to increase the frequency or processor time for more stable operation

stephenw10

The quality value shown in brackets denotes the accuracy of the timecounter source which is why HPET was chosen by default. That can be a problem when all the hardware is virtual, some may be virtualised better than others for whatever reason.

I can't really advice you on KVM settings directly. I would think anything that is different to the host CPU is going to require more processing from the hypervisor. Passing CPU cores directly to the VM is probably better. But as I say I don't use KVM so that's speculation. I'm sure there are others here who can give better advice there.

@stephenw10 Hi Stephen. UI and console was resopnsive after 15 hours and stable work

stephenw10

Cool. So which timecounter did you end up using for reference?

Steve

john_wick

@stephenw10 I just add kern.timecounter.hardware=ACPI-fast from web UI in tunables and reboot the PFsense VM :)
