            <title>[DRIVERS-2236] CMAP inconsistency when clearing load balanced pools </title>
                <link>https://jira.mongodb.org/browse/DRIVERS-2236</link>
                <project id="10980" key="DRIVERS">Drivers</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/DRIVERS-1942&quot; title=&quot;Clarify clearing behavior for load balanced pools&quot; class=&quot;issue-link&quot; data-issue-key=&quot;DRIVERS-1942&quot;&gt;DRIVERS-1942&lt;/a&gt; added the following clarification to the CMAP spec section describing the &lt;a href=&quot;https://github.com/mongodb/specifications/blob/master/source/connection-monitoring-and-pooling/connection-monitoring-and-pooling.rst#clearing-a-connection-pool&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&quot;Clearing a Connection Pool&quot; method&lt;/a&gt;:&lt;/p&gt;

&lt;blockquote&gt;&lt;p&gt;This method MUST NOT be used in load balancer mode.&lt;/p&gt;&lt;/blockquote&gt;

&lt;p&gt;If the pool.clear() method is not used, then load balanced pools will never emit PoolClearedEvents. However, there is a load balancer spec test which asserts that a PoolClearedEvent is emitted after a connection handshake failure:&lt;br/&gt;
&lt;a href=&quot;https://github.com/mongodb/specifications/blob/008d2f5/source/load-balancers/tests/sdam-error-handling.yml#L175-L205&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/specifications/blob/008d2f5/source/load-balancers/tests/sdam-error-handling.yml#L175-L205&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;What should a driver do when clearing a load balanced pool without a serviceId (eg when the initial hello command fails)? Is the load balancer test simply out of date?&lt;/p&gt;</description>
