                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Before&#160;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-58991&quot; title=&quot;Acquire the critical section on the recipient shard of a moveChunk operation&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-58991&quot;&gt;&lt;del&gt;SERVER-58991&lt;/del&gt;&lt;/a&gt;, the &apos;step 7&apos; of the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/ff63018141242e609f57b60888ab7605a5e20d2c/src/mongo/db/s/migration_destination_manager.cpp#L1090-L1091&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;MigrationDestinationManager timing&lt;/a&gt; object&#160;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/ff63018141242e609f57b60888ab7605a5e20d2c/src/mongo/db/s/migration_destination_manager.cpp#L1549&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;used to account up until the session cloner had finished&lt;/a&gt;. After &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-58991&quot; title=&quot;Acquire the critical section on the recipient shard of a moveChunk operation&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-58991&quot;&gt;&lt;del&gt;SERVER-58991&lt;/del&gt;&lt;/a&gt;, in addition to that, it now &lt;a href=&quot;https://github.com/mongodb/mongo/blob/ff63018141242e609f57b60888ab7605a5e20d2c/src/mongo/db/s/migration_destination_manager.cpp#L1618&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;also accounts for the time the MigrationDestinationManager waits for the release of its critical section&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;We should restore the former semantics of &apos;step 7&apos;; and introduce a new &apos;step 8&apos;, which exists only when the new migration protocol is in use that is stepped after the critical section has been exited.&lt;/p&gt;</description>
