Do you have the full crash report?

You can upload it here so I can check it: https://nc.netgate.com/nextcloud/s/fpRokRoTPfjoHKN

Hmm, two completely different crashes there:

That second one is associated with a Snort coredump. Do you have the current Snort package installed?

Have you seen more crashes? Are they also different? Numerous different crashes are usually a hardware issue.

That aside it looks like you have Snort, Suricata and Zeek installed and you should only ever use one of those.

You have some invalid sysctl settings:

<118>Setting up extended sysctls...sysctl: oid 'net.isr.maxthreads' is a read only tunable
<118>sysctl: Tunable values are set in /boot/loader.conf
<118>sysctl: oid 'net.isr.numthreads' is read only
<118>sysctl: oid 'net.isr.maxthreads' is a read only tunable
<118>sysctl: Tunable values are set in /boot/loader.conf
<118>sysctl: oid 'net.isr.numthreads' is read only

Those are loader tunables as it shows there.

@stephenw10 i have all of them installed (snort, zeek, suricata) but none of them activated simultaneously with each other. Just for testing. I will remove them and keep only one.

For the tunables i have them fir wireguard tweaking - found somewhere.
Thanks for the analysis of my crash logs.

AlexanderK

@stephenw10 while removing packages - suricata system crashed again...

stephenw10

Same crash or a new different one?

If it's different again I would run a ram test.

@stephenw10 said in pfsense crashes lately - how can i analyze logs?:

Same crash or a new different one?

If it's different again I would run a ram test.

can i upload them?

stephenw10

Yes, same link should still work.

AlexanderK

@stephenw10 thanks again. uploaded them

stephenw10

Yup, two completely different crashes again. I would definitely do a memory test here as a next step. A software bug would not present such widely varying crashes.
