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/transaction_coordinator.cpp:627: MISSING_LOCK 183912 Accessing "this->_participantsDurable" without holding lock "mongo::TransactionCoordinator._mutex". Elsewhere, "mongo::TransactionCoordinator._participantsDurable" is written to with "TransactionCoordinator._mutex" held 1 out of 2 times (1 of these accesses strongly imply that it is necessary).
