            <title>[SERVER-27078] Race in ShardRegistry initialization causes it to not update the config server connection string</title>
                <link>https://jira.mongodb.org/browse/SERVER-27078</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Description of race:&lt;/p&gt;

&lt;ol&gt;
	&lt;li&gt;Start mongos with just a single node specified in --configdb&lt;/li&gt;
	&lt;li&gt;ShardRegistry::init() gets called.&lt;/li&gt;
	&lt;li&gt;ShardFactory::createShard gets called for &quot;config&quot; and the initial config server seed string (&lt;a href=&quot;https://github.com/mongodb/mongo/blob/r3.4.0-rc2/src/mongo/s/client/shard_registry.cpp#L186&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;ref&lt;/a&gt;).&lt;/li&gt;
	&lt;li&gt;The ReplicaSetMonitor for the config replica sets gets created.&lt;/li&gt;
	&lt;li&gt;ReplicaSetMonitor (RSM) reload thread discovers the other nodes in the CSRS.&lt;/li&gt;
	&lt;li&gt;RSM tries to update the ShardRegistry via the synchronous update hook. However, it fails to update because the &quot;config&quot; entry hasn&apos;t been created yet (&lt;a href=&quot;https://github.com/mongodb/mongo/blob/r3.4.0-rc2/src/mongo/s/client/shard_registry.cpp#L458-L460&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;ref&lt;/a&gt;).&lt;/li&gt;
	&lt;li&gt;ShardRegistry populates the &quot;config&quot; shard entry (&lt;a href=&quot;https://github.com/mongodb/mongo/blob/r3.4.0-rc2/src/mongo/s/client/shard_registry.cpp#L187&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;ref&lt;/a&gt;).&lt;/li&gt;
&lt;/ol&gt;

                            <customfieldvalue>&lt;p&gt;Build a custom mongos with this change: add a sleepsecs(5) right before this line:&lt;/p&gt;

&lt;ol&gt;
	&lt;li&gt;Deploy config server replica sets with 3 members&lt;/li&gt;
	&lt;li&gt;Run mongos, but only pass one of the members in the configdb parameter. Example:
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;

		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;./mongos --port 20005 --configdb test-configRS/ren-desktop:20001&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;&lt;/li&gt;
&lt;/ol&gt;
