Azure Container Instance was terminated by Service Fabric with Exit Code 7147, won't start, stuck in Pending state

Question

A few of my Container Instances were shut down at 4am today by Service Fabric, with exit code 7147.

Subsequent attempts to restart the container are failing even 6 hours (!) after the initial shutdown event. The container status remains in "Pending" or "Repairing" state, with no apparent way to resolve the situation. I fully understand that this situation may occur periodically for maintenance or load-balancing on Azure. However, why do container instances take so long to start again? What does Microsoft provide as solution or tools to further investigate this issue and to speed up the recovery of Container Instances availability after such events? Thank you.
