I think it might be related to IPv6?

@gtr_991 if you feel its ipv6 related - could be this?

https://redmine.pfsense.org/issues/14164

Has it happened more than once? My understanding this redmine has been addressed in 23.05 and its pretty close to be released, if your seeing this quite a bit maybe you might want to update to 23.05 a bit early?

[GTR_991]

@johnpoz yes, today it has been super unstable, already the system paniced/rebooted like 7 times since 5 hours.

anything can be done meanwhile? beside updating to snapshots..

Thanks in advance,

[johnpoz]

@gtr_991 if it was me, and its ipv6 related - I would just turn off IPv6.. then its kind of hard to cause a problem?

Do you actually have some "need" for IPv6 - are you hosting or providing services inbound on ipv6? Or just outbound - because I for the life of me can not find any sort of resource that is only available via IPv6..

[GTR_991]

@johnpoz I dont actually require IPv6 connectivity, i just use it outbound.
I disabled IPv6 for testing.
i will report back by tomorrow.

[johnpoz]

@gtr_991 sounds like a very reasonable plan.. Maybe turn it back on trmw and if you start seeing the same crashes then need to look deeper into what could be causing that.

Strange that you were working fine before? And now like 7 times in a 5 hours? wonder what is triggering it, that was happening before?

[GTR_991]

@johnpoz For sure i will do it.

Honestly im not even sure, i was running openwrt previously then i installed pfsense plus around 2 days back, the first 24 hours it was very stable then suddenly the crashes started to happen around the 2nd day of install, it kept happening more and more often where in the past 5 hours it was crashing each hour. could it be something related to pfblockerNG?
BTW I think the only thing i changes i did by the 2nd day of installation , i changed the DNS setting to forwarding mode using TLS with custom DNS. might be related?

[johnpoz]

@gtr_991 said in crash report-random reboot.:

DNS setting to forwarding mode using TLS with custom DNS. might be related?

I not a fan of dot or doh - they do nothing for me.. I just resolve.. But many users seem to love handing all their dns over to providers ;)

There has been issues with dnssec being enable when you forward, where issues with dns - but have not heard of crashes because of it, etc. And some discussion around IPv6... I would see how it works with IPv6 just off - but if your forwarding be it over dot or just normally there is no point to asking for dnssec - where you forward is either doing dnssec or it isn't - you having that set is just going to be problematic in the long run without any benefit.

It's this: https://redmine.pfsense.org/issues/14077

Fixed in 23.05/2.7

[GTR_991]

Crashes seems stopped after disabling IPv6.

is there any timeframe when the build 23.05 will be released on stable channel?

[stephenw10]

Well it's targeted for May 2023. However that's always dependent on testing, new issues etc.

[GTR_991]

Been almost 24 hours and its running stable..

[stephenw10]

Yeah, if you've removed the IPv6 traffic that was triggering it you should be fine. 23.05 is not far off now anyway.
