Wan periodic reset causes system reboot.

disabling ipv6 seems to fix the issue!

Ok, seems like the issue I ran into at the redline link above.
I need IPv6 so waiting on a fix is my only option.

No that shows you do have SWAP enabled so I'd expect to see a crash report if it suffered a kernel panic. And your description sounds like a kernel panic. It spews the full process backtrace and message buffer onto the console before rebooting.
We need to see the initial backtrace and panic string when that happens really. Since you can trigger it on demand, can you hook up a serial console to log it?
If not you should be able to stop the auto reboot and scroll back through the buffer with the scroll-lock key at a vga/keyboard console. -
Are you running tailscale?
-
@stephenw10 yes i am running tailscale
-
I have IPv6 (from BT) over PPPoE which seems like it should be nearly identical to connections that are hitting this but I cannot trigger it.
There any special trick I'm missing? -

Ooo, try disabling that and see if you can still trigger it.

@stephenw10 how i can stop the auto reboot?
-
@stephenw10 my tailscale is not enabled

after enabling again ipv6 the problem seems to be solved. really strange situation

For me it is intermittent, with it rebooting 50-60% of the time.

Edit /etc/pfSense-ddb.conf and remove or comment 'reset' from the script kdb.enter.default line.
Then after a panic the console will remain at the db prompt:
db:0:kdb.enter.default> capture off db:0:kdb.enter.default> textdump dump Textdump complete. db>You can then scroll back to see the backtrace shown after
db:1:pfs> bt.You will want to restore the reset command to the file after doing that though because otherwise it will not reboot after a panic at 3am which is probably not what you want!

thanks steve made that change but now it has been resolved. let's see what will happen#update reboot happened
the console didn't remain at the db prompt.
I suppose it is something different

It happened....i will try to upload everything
crash log was huge.
i took some photos but couldn't upload here because the size is big

Yes it's big! The interesting part is right at the beginning of the report. For example:

Yours will probably be similar to that shown in the bug report linked above.
Unfortunately those pictures are all from after that part. -

What i can do to help ? -
Are you not able to scroll back far enough to see the initial backtrace?
pfSense doesn't use the standard log conf file it uses: /var/etc/syslog.d/pfSense.conf
So you'd have to try that there instead. I have never tried that.Steve
-
@stephenw10 the first picture was the highest i could go....
So it is not possible.
I will try the log -
Hmm, still odd that it doesn't save the panic as a crash report by default. The only reasons that wouldn't happen I can think of are if there's no SWAP configured (there is) or if the drive is failing and it's inaccessible at that point.
