Max suggests the following: "I would say the InterruptedAtShutdown exception likely came from https://github.com/mongodb/mongo/blob/7060765f3e0d33b74b2f6c7764fb3e88ece3b805/src/mongo/idl/cluster_server_parameter_refresher.cpp#L289 where the SharedLock acquisition in https://github.com/mongodb/mongo/blob/7060765f3e0d33b74b2f6c7764fb3e88ece3b805/src/mongo/db/query/query_settings_manager.cpp#L167 threw because the server shutdown sequence was started and that causes all OperationContexts to report as being interrupted https://github.com/mongodb/mongo/blob/7060765f3e0d33b74b2f6c7764fb3e88ece3b805/src/mongo/db/operation_context.cpp#L244-L247"
