            <title>[SERVER-46371] Error messages and logging should not assume collection was dropped and recreated on epoch change</title>
                <link>https://jira.mongodb.org/browse/SERVER-46371</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There are a few places where we log or return an error message when a sharded collection&apos;s epoch changes that assume the collection was dropped and recreated (e.g. &lt;a href=&quot;https://github.com/mongodb/mongo/blob/0d083cfc66abb8804ca5b80c8b2cea534434099b/src/mongo/db/s/config/sharding_catalog_manager_chunk_operations.cpp#L1136-L1137&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;). Previously this was correct, but as of 4.4 refining a collection&apos;s shard key can also change the epoch, so such messages/logs are misleading and should be updated.&lt;/p&gt;</description>
