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/session/logical_session_cache_impl.cpp:326: MISSING_LOCK 151561 Accessing "this->this->_endingSessions" without holding lock "mongo::LogicalSessionCacheImpl._mutex". Elsewhere, "mongo::LogicalSessionCacheImpl._endingSessions" is written to with "LogicalSessionCacheImpl._mutex" held 1 out of 1 times.
