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/storage/collection_markers.cpp:523: MISSING_LOCK 169041 Accessing "this->collectionMarkers->_minBytesPerMarker" without holding lock "mongo::CollectionTruncateMarkers._markersMutex". Elsewhere, "mongo::CollectionTruncateMarkers._minBytesPerMarker" is written to with "CollectionTruncateMarkers._markersMutex" held 1 out of 1 times (1 of these accesses strongly imply that it is necessary).
