Foreman » Smart Proxy

This crash seems to happen most often (but not always) when trying to provision a new host, but it also seems to happen randomly. There is also a warning in the logs about the FreeIPA realm plugin and xmlrpc that looks unrelated to me. This is from the foreman-proxy journal ( journalctl -efu foreman-proxy.service ):

The logs in /var/log/foreman-proxy/proxy.log don't show anything about the crash.

This is happening on the Foreman machine itself (i.e. it runs Foreman and Foreman-Proxy). These are the features enabled on that proxy instance: DNS, Realm, Discovery, TFTP, Logs, and HTTPBoot.

The crashes started with version 3.12.1 after we upgraded the machine from Ubuntu 20.04 to 22.04. We then upgraded to Foreman 3.13.0 in the hopes that this will contain a fix for the crash, but unfortunately it keeps happening. The above journal excerpt is from Foreman-Proxy 3.13.0, on Ubuntu 22.04.

As mentioned the crashes happen most often when trying to provision a new host; I am guessing two out of three times.

Please let me know what, if any, information I can provide and how to help debug this.
