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/repl/replication_coordinator_external_state_impl.cpp:544: MISSING_LOCK 154619 Accessing "this->_workerPool" without holding lock "mongo::repl::ReplicationCoordinatorExternalStateImpl._threadMutex". Elsewhere, "mongo::repl::ReplicationCoordinatorExternalStateImpl._workerPool" is written to with "ReplicationCoordinatorExternalStateImpl._threadMutex" held 1 out of 1 times.
