Description

When running the installer, I got the following error

 /Stage[main]/Foreman_proxy::Register/Foreman_smartproxy[centos7-foreman-nightly.wisse.example.com]: Could not evaluate: Proxy centos7-foreman-nightly.wisse.example.com cannot be retrieved: unknown error (response 500)

After looking for the error in /var/log/foreman/production.log, I couldn't find anything. A closer look showed me the following in /var/log/httpd/error_log:

[ 2020-02-05 10:39:03.8030 21530/7f0770143700 Pool2/Implementation.cpp:287 ]: Could not spawn process for application /usr/share/foreman: An error occured while starting up the preloader.

[ 2020-02-05 10:39:03.8076 21530/7f076dbba700 agents/HelperAgent/RequestHandler.h:2306 ]: [Client 20] Cannot checkout session because a spawning error occurred. The identifier of the error is 91ebc548. Please see earlier logs for details about the error.

This is a bad user experience because before we rarely if ever got users to look in that file but I'm not sure where we should fix this (Foreman, Installer, Packaging) so I created the issue in Foreman for now.

Looking at the code, this is the result of a 'raise' with nothing catching it which is fine. However, I could this being more obvious if we add logger statements before the raise to ensure it appears in the production log?

Another thing you see is that both dynflow workers get in a restart loop because systemd doesn't figure out it'll never work. On Katello it'll be 3 processes meaning you get 300% CPU usage.

I've now worked around this by changing the seeding script to ignore it, but as a normal user I wouldn't know how to solve this.

Would it make sense to have a generic catch in the initializer to catch any seed errors that aren't properly handled? maybe show a ui notification with the message and telling users they need to manually rerun the seed?
