@chrskrchr We are still blocked by missing CLA on #3529 and it should be signed first especially since all the code were copied from there.

@IvanGoncharov - at what point would we consider #3529 abandoned? I don't want to prevent @asztal from getting credit for their great fix, but that PR was opened nearly 2 months ago and we'd like to get this fix rolled out to our production service as quickly as possible. (and remove some bandaids we wrapped around the issue to prevent it from causing a process exit)

Closing this and re-submitting as a new PR per the guidance in #3651.
