            <title>[SERVER-75637] Use &apos;retryWrites&apos; when directly writing to the CSRS in `merge_all_chunks_on_shard.js`</title>
                <link>https://jira.mongodb.org/browse/SERVER-75637</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/39f7c9035ab26b15b95625e016da51be946374a2/jstests/sharding/merge_all_chunks_on_shard.js#L43-L50&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;An updateMany&lt;/a&gt; is performed to override the &lt;tt&gt;onCurrentShardSince&lt;/tt&gt; field on chunk documents.&lt;/p&gt;

&lt;p&gt;When the config server steps down while serving the request the client could get a write concern error as the following:&lt;/p&gt;

&lt;p/&gt;

&lt;p&gt;Changing the updateMany to happen as a part of a session with &lt;tt&gt;retryWrites:true&lt;/tt&gt; would solve the issue.
