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/client/sdam/topology_listener.cpp:236: MISSING_LOCK 141808 Accessing "event.type" without holding lock "mongo::sdam::TopologyEventsPublisher._eventQueueMutex". Elsewhere, "mongo::sdam::TopologyEventsPublisher::Event.type" is written to with "TopologyEventsPublisher._eventQueueMutex" held 7 out of 7 times.
