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_impl.cpp:5373: MISSING_LOCK 175036 Accessing "this->_oplogSyncState" without holding lock "mongo::repl::ReplicationCoordinatorImpl._mutex". Elsewhere, "mongo::repl::ReplicationCoordinatorImpl._oplogSyncState" is written to with "ReplicationCoordinatorImpl._mutex" held 6 out of 8 times.
