/opt/theforeman/tfm/root/usr/share/gems/gems/dynflow-0.8.10/lib/dynflow/dispatcher/client_dispatcher.rb:37 I'm filing a separate bug for this one, as the "undefined method `cp_config' for" in the original bug has different fix. Version-Release number of selected component (if applicable): How reproducible: Occasionally (race-condition kind of bug) Steps to reproduce described in: https://bugzilla.redhat.com/show_bug.cgi?id=1320794 watch /var/log/foreman/dynflow_executor.output for the segfaults Additional info:
Proposed fix https://github.com/Dynflow/dynflow/pull/185
I went several times through steps described in https://bugzilla.redhat.com/show_bug.cgi?id=1320794#c0 and I did not run into any segfaults. Verified on RHEL 7, snap 13.1
