Suricata crashing

[jan.stasik]

Hello,
I am Currently running OPNsense 23.4.2, Business Edition, running it on ESXi. After the upgrade to this version Suricata is crashing after some time when is enabled. Here is what i see in logs. VMX1 is my internet facing port.
How can be this fixed? And how to get rid of warnings.

I also get

 App-Layer protocol rdp enable status not set, so enabling by default. This behavior will change in Suricata 7, so please update your config. See ticket #4744 for more details.

I tried to reinstal, but seems like a lot of config conflicts:

I tried reinstalling suricata module, disabling and reenabling it...and now I get a bunch of other errors. Could this be related to ACME LE module? It is only used to get rid of SSL warning when acessing Web GUI.

original comment removed

this requires modifying the suricata.yaml file to include the correct sections for the mentioned App-Layer protocols which are missing, this is a best practice since the behavior will change in the future and the protocols will no longer be auto-enabled


"This behavior will change in Suricata 7, so please update your config"



if you have not tweaked the suricata.yaml file, consider looking for a suricata.yaml from a more recent versions


check if these sections are present as such in suricata.yaml, consider adding them at the appropriate place
