            <title>[SERVER-26840] ChunkManager reload may return successfully if the chunk metadata is corrupted</title>
                <link>https://jira.mongodb.org/browse/SERVER-26840</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The chunk manager may &lt;a href=&quot;https://github.com/mongodb/mongo/blob/e8cbb32624663fdf59f6df752594e5295c55247c/src/mongo/s/chunk_manager.cpp#L234&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;return early&lt;/a&gt; if the chunk metadata is corrupted (i.e., contains holes or mismatched keys).&lt;/p&gt;

&lt;p&gt;It is not certain whether any corruptions will not already have been discovered by the incremental reload&apos;s logic in the &lt;tt&gt;_load&lt;/tt&gt; method, but for the sake of not introducing a regression the early return should be removed.&lt;/p&gt;

&lt;p&gt;The bug was introduced by &lt;a href=&quot;https://github.com/mongodb/mongo/commit/e8cbb32624663fdf59f6df752594e5295c55247c&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this commit&lt;/a&gt; and is only present in 3.4.0-RC2.&lt;/p&gt;</description>
