pfSense Plus and SG-3100

@va3mw you'll need to backup your config and re-install pfSense 2.4.5. See https://docs.netgate.com/pfsense/en/latest/solutions/sg-3100/reinstall-pfsense.html

Ahh, I've been experiencing the "wonkiness" today, so I'm glad it's not just me.

If someone has already upgraded, and doesn't really want to downgrade, is there any other workaround, or is it basically just restarting the firewall to get it operational again?

You can disable one CPU core and it will avoid ever hitting the lock. Obviously performance will be reduced but that may not be an issue for a lot of use cases. Run:

echo hw.ncpu=1 >> /boot/loader.conf.local

Then reboot.

Remove or comment out that line later after this is fixed.

Done and done. Thank you Steve!

Will updates on the update be placed in this thread (that I'm watching)?

stephenw10 · Feb 20, 2021, 7:07 PM

Yes, this thread will be updated.

Did this work for you? Im stuck rebooting randomly during the day also.

@mr_aj

Just added this entry to the file a few minutes ago, so we'll see!

I only had a single failure requiring a reboot during the day today...so I was hoping to avoid experiencing that again.

Glad there's a quick and easy workaround.

@mr_aj So far so good for me, 3 hrs in on a single cpu.

All is well with this quick fix. Thanks!

Good to hear.

We think we have found the root cause of this and will be testing fixes imminently.

@artooro Thanks. That is what I did.

@stephenw10
Is there a possibility to 'upgrade´ from the 21.02 to the new one without having to downgrade first? I am experiencing the problem, as in not being able to retrieve any packages. Or is the only way to do a downgrade first and then upgrade later? Can I export my settings from my current 21.02 one and import them again when I upgrade?

Thanks for your guys work on this. Much appreciated

stephenw10 · Feb 21, 2021, 3:10 PM

Yes, I expect it to be 21.02_1 or similar when made available. You should be able to upgrade to it from either 2.4.5p1 or 21.02.
Yes, the config version will be the same but you can always import an older config into a newer pfSense version anyway. You will be able to here.

@stephenw10
Does that mean that the url mentioned earlier in this thread will be up and running?

stephenw10 · Feb 21, 2021, 5:14 PM

The pkg server? Yes, it will be. When it's available the update should show on the dashboard like any previous update.

i went to diagnostics > command prompt and ran the command. got the green success screen i guess you call it and then rebooted

after a reboot when i go to diagnostics > edit file > open loader.conf nothing has changed.
do you have to use the console or SSH for this to complete?

stephenw10 · Feb 23, 2021, 2:31 PM

It doesn't add it to loader.conf which might get overwritten.

/boot/loader.conf.local

@stephenw10

I really appreciate the effort to root cause this, and for the easy workaround -- thank you!

What is the typical turn-around for pushing out a hotfix like this, if nothing goes wrong during testing? I've been holding-off on downgrading to 2.4.5 thinking a fix may be landing soon.

I put in the ncpu work-around after the bug started disrupting work meetings and online schooling, but it does cause the WAN bandwidth to max out at ~650Mbps.

stephenw10 · Feb 25, 2021, 6:34 PM

Very soon.
We are testing new images now. I've been hammering the SG-3100 with traffic that easily triggered this before and it seems solid so far.

prosaicorsair · Feb 25, 2021, 6:34 PM

New version for SG-3100 is out and I see it available for download. Will be happy to have multicore back.
