Data race condition

The value of the shared data will be determined by the interleaving of thread execution. Thread shared data is accessed without holding an appropriate lock, possibly causing a race condition
/src/mongo/db/s/sharding_ddl_coordinator_service.cpp:290: MISSING_LOCK 153859 Accessing "this->this" without holding lock "mongo::ShardingDDLCoordinatorService._mutex". Elsewhere, "mongo::ShardingDDLCoordinatorService::_rebuildService(std::shared_ptr<mongo::executor::ScopedTaskExecutor>, mongo::CancellationToken const &)::[lambda() (instance 1)].this" is written to with "ShardingDDLCoordinatorService._mutex" held 1 out of 1 times.
