            <title>[SERVER-38580] Tighten the check around when the `refreshing` flag is supposed to have been cleared on a secondary node</title>
                <link>https://jira.mongodb.org/browse/SERVER-38580</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;From a failed Evergreen run we have seen a case where un-setting of the &apos;refreshing&apos; flag did not happen somehow on the secondaries, even though the refresh succeeded on the primaries.&lt;/p&gt;

&lt;p&gt;It is extremely unlikely that the two writes in &lt;tt&gt;persistCollectionAndChangedChunks&lt;/tt&gt; failed and without this, there is no explanation of why the notification &lt;a href=&quot;https://github.com/mongodb/mongo/blob/47826721dd85248b8acb569694687db0e71257cd/src/mongo/db/s/shard_server_op_observer.cpp#L76&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt; never got signaled.&lt;/p&gt;

&lt;p&gt;We should change the wait loop in &lt;a href=&quot;https://github.com/mongodb/mongo/blob/47826721dd85248b8acb569694687db0e71257cd/src/mongo/db/s/shard_server_catalog_cache_loader.cpp#L1065&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;_getCompletePersistedMetadataForSecondarySinceVersion&lt;/tt&gt;&lt;/a&gt; to have a timeout of a few seconds between loop and after which it should check whether the optime returned by the primary&apos;s refresh has been reached and assert that the refreshing flag has been cleared. If it hasn&apos;t been cleared, it should log the contents of the &lt;tt&gt;config.cache.collections&lt;/tt&gt; entry for the collection being refreshed and failing the refresh (which will cause the client calls to fail).&lt;/p&gt;

&lt;p&gt;This should help us build further hypothesis about this issue.&lt;/p&gt;</description>
