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:538: MISSING_LOCK 145286 Accessing "this->_writerPool" without holding lock "mongo::repl::ReplicationCoordinatorExternalStateImpl._threadMutex". Elsewhere, "mongo::repl::ReplicationCoordinatorExternalStateImpl._writerPool" is written to with "ReplicationCoordinatorExternalStateImpl._threadMutex" held 1 out of 1 times.
