We are so far unable to get scout_apm to work. Error is

fatal - machine stack overflow in critical region:

No other backtrace shows in rails server.

scout_apm 4.0.4
ruby 3.0.0
rails 6.0.3.5

What additional information can I provide that would be helpful?

@sposin My hunch is this could only be caused by a C extension somehow. In the Scout agent we have 2 extensions - one that tracks object allocations, and one that reports the amount of memory used. Would you be able to share your Gemfile and Gemfile.lock (you can send it to us at support@ )?

This turns out to be an issue with a combination of the remotipart gem which is a dependency of rails_admin, which makes the wicked_pdf gem render calls go haywire. The workaround is to use wicked_pdf 1.4.0 or to not use rails_admin to avoid the remotipart render issues.

Here's a stacktrace I was able to reproduce:
