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/ftdc/controller.cpp:211: MISSING_LOCK 111978 Accessing "this->_config" without holding lock "mongo::FTDCController._mutex". Elsewhere, "mongo::FTDCController._config" is written to with "FTDCController._mutex" held 2 out of 2 times (1 of these accesses strongly imply that it is necessary).
