Pfsense crashing randomly pfsnese plus 24.03
-
@ssjucrono As we're experiencing the same (same signature, same Redmine bug to track, another forum Topic though) I'd be interested .. do you run any of the following packages:
- acme
- aws-wizard (pre-installed on pfsense+)
- frr
- ipse-profile-wizard (pre-installed on pfsense+)
- netgate_firmware_upgrade (pre-installed on pfsense+)
- node_exporter
- openvpn-client-export (pre-installed, I think)
- zabbix-agent64

Thank you! yes I run these 2. though I can remove openvpn as I do not use it anymore. I have switched to tailscale
acme
openvpn-client-export -
@ssjucrono no no. Don’t remove anything. I was just interested if there might be some similarities to our setup.
I think those 2 packages are pretty unspectacular given they’re not really doing „anything network“
-
@cboenning
yeah, I don't need them. I removed acme and openvpn exporter as I have never used them.thank you
-
@ssjucrono you may want to opt in to enabling „full core dumps“ as outlined here (https://forum.netgate.com/topic/188861/24-03-crashing-again/19) and provide them to @stephenw10 and/or Redmine to get this debugged eventually though.
-
Yup, that. If you're able to enable full core dumps that will help a lot here. However be aware that you need to have enough SWAP available for the dump file which will be the size of the used RAM.
An alternative that may also help would be to run the debug kernel:
https://docs.netgate.com/pfsense/en/latest/troubleshooting/debug-kernel.html
That may show additional errors before the panic.
-
@ssjucrono you may want to check the Redmine issue for a workaround (https://redmine.pfsense.org/issues/15684#note-14)
-
Yup let us know if disabling
net.inet.tcp.sack.enableworks to prevent it.For reference that looks like:

@stephenw10 Thank you for the update. I don't have net.inet.tcp.sack.enable in my system tunables? should I add it? or just leave it as is?
-
Yes you will need to add that. It's not a default tunable.
-
@stephenw10 I have not seen this crash in awhile. I will set this though.
Maybe it was caused by my Unraid Docker Containers being backed up each night. So they are all stopped and then started within about 12minutes. I do get a flapping warning from arpwatch each night when this occurs. Perhaps that was the cause of the initial crash?
-
I doubt it. But it's unclear what actually triggers it since most users never hit it.

It works. I had random crashes, but once I added "net.inet.tcp.sack.enable=0", I haven't experienced any crashes.
-
Great. That should be patched in the next release.
