> The following sequence of events lead to deadlock:
> # testasynccollectioncreation_shard1_0_replica2 (core_node5) becomes active
> # OCP asks sub-shard leader testasynccollectioncreation_shard1_0_replica1 to
> wait until replica2 is in recovery
> At this point, the test just keeps pinging for status until timeout and fails.
