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/file_writer.cpp:167: MISSING_LOCK 144753 Accessing "this->_config->maxSamplesPerInterimMetricChunk" without holding lock "mongo::FTDCController._mutex". Elsewhere, "mongo::FTDCConfig.maxSamplesPerInterimMetricChunk" is written to with "FTDCController._mutex" held 1 out of 1 times (1 of these accesses strongly imply that it is necessary).
