            <title>[SERVER-43949] Check for term equality when comparing OpTime for a writeConcern</title>
                <link>https://jira.mongodb.org/browse/SERVER-43949</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;tt&gt;haveNumNodesReachedOpTime&lt;/tt&gt; and &lt;tt&gt;haveTaggedNodesReachedOpTime&lt;/tt&gt; currently use OpTime comparison functions defined &lt;a href=&quot;https://github.com/mongodb/mongo/blob/e3c434d49714eb460b5c35b9d9202cf88082b743/src/mongo/db/repl/optime.h#L122-L150&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;. But if a OpTime with a higher term comes via heartbeat, we shouldn&apos;t consider that as a writeConcern satisfaction. So we should also check for term equality before waking up writeConcern waiters. If a higher term comes, it means that the node will be stepping down. And on member state changes after the stepDown, the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/e3c434d49714eb460b5c35b9d9202cf88082b743/src/mongo/db/repl/replication_coordinator_impl.cpp#L2816-L2818&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;existing logic&lt;/a&gt; should be able to wake up all remaining waiters with stepDown errors.&lt;/p&gt;</description>
