                <link>https://jira.mongodb.org/browse/SERVER-64411</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Added in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-63090&quot; title=&quot;Recipient garbarge collects itself on primary step up &quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-63090&quot;&gt;&lt;del&gt;SERVER-63090&lt;/del&gt;&lt;/a&gt;, when calling _cleanRecipientStateDoc we need to anchor the service to make sure it is not gone by the time we get out of scope when running on the asyncTry. This is due to the fact that the OpObserver will see that the state document gets deleted and will no longer run the service.&lt;br/&gt;
 The solution is to add an anchor since &lt;a href=&quot;https://github.com/10gen/mongo/blob/659ed4c8593016dc7157c0117de18ce916ef8d42/src/mongo/db/serverless/shard_split_donor_service.cpp#L881&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;it is missing&lt;/a&gt;.&lt;/p&gt;</description>
