            <title>[SERVER-47477] Sharded logical sessions cache refresh ignores failure to update or delete session records</title>
                <link>https://jira.mongodb.org/browse/SERVER-47477</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;To refresh or remove session records from the logical sessions collection, the sharded logical sessions cache (i.e. on a mongos or shard server) uses lambdas that run bulk writes through the ClusterWriter (&lt;a href=&quot;https://github.com/mongodb/mongo/blob/c4bca20e65afbb77834559247bdda8f541cda16b/src/mongo/db/sessions_collection_sharded.cpp#L145-L146&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt; and &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c4bca20e65afbb77834559247bdda8f541cda16b/src/mongo/db/sessions_collection_sharded.cpp#L164-L165&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;). These lambdas return the status from each write&apos;s response, but when the lambda is invoked, &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c4bca20e65afbb77834559247bdda8f541cda16b/src/mongo/db/sessions_collection.cpp#L108-L115&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;the return value is ignored&lt;/a&gt;, so if either write fails, the refresh will not notice and continue running, which&#160;can lead to incorrectly killing the sessions of recently established cursors.&lt;/p&gt;

&lt;p&gt;It looks like this was introduced by&#160;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-42508&quot; title=&quot;Convert SessionsCollection to throw instead of return status&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-42508&quot;&gt;&lt;del&gt;SERVER-42508&lt;/del&gt;&lt;/a&gt;, so it should only affect 4.4 and the current master.&lt;/p&gt;</description>
