            <title>[SERVER-58489] Collection creation stuck in an infinite writeConflictRetry loop when having a duplicate name as a view</title>
                <link>https://jira.mongodb.org/browse/SERVER-58489</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When creating a collection implicitly, we check &lt;a href=&quot;https://github.com/mongodb/mongo/blob/master/src/mongo/db/ops/write_ops_exec.cpp#L231&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;if a collection with the namespace string already exists&lt;/a&gt;. However, before committing, we also check that &lt;a href=&quot;https://github.com/mongodb/mongo/blob/master/src/mongo/db/catalog/collection_catalog.cpp#L929&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;if the nss conflicts with another view&lt;/a&gt;. As a result, if one thread successfully creates a view while another one is attempting to create a collection with the same nss in the writeConflictRetry loop, the other thread could fall into an infinite loop.&lt;/p&gt;</description>
