                    <description>&lt;p&gt;This bug manifests itself as &lt;/p&gt;
&lt;p/&gt;

			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;
&lt;p&gt;in the logs of the secondaries on the config server during upgrade 3.4 -&amp;gt; 3.6 after binaries are upgraded but FCV is still 3.4.&lt;br/&gt;
The issue is that in FCV 3.4 mongod does NOT attach operationTime to not confuse drivers (&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-29785&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/SERVER-29785&lt;/a&gt;) &lt;br/&gt;
But  setupSessionsCollection that is scheduled by LogicalSessionsCache  invokes &lt;/p&gt;

			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;
&lt;p&gt;that uasserts because it can not parse the operationTime from the response it gets from the primary because primary is FCV3.4&lt;/p&gt;

&lt;p&gt;the bottomline:&lt;br/&gt;
The check for FCV 3.4 can be put anywhere in the chain listed above to prevent the logs. The actual bug seems in the design of forcePrimaryRefreshAndWaitForReplication that returns the parsing error of successfully executed command as the command execution error. In the reality the config.system.sessions collection is created successfully.&lt;/p&gt;</description>

                            <comment id="1980477" author="kaloian.manassiev" created="Mon, 20 Aug 2018 18:19:13 +0000"  >&lt;p&gt;Starting with version 3.6.7 (and specifically with the &lt;a href=&quot;https://github.com/mongodb/mongo/commit/646d68003cadcd60fed5abaf1e92368390a4a1cb&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;fix&lt;/a&gt; for &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-36248&quot; title=&quot;Do not reject sessions in FCV 3.4&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-36248&quot;&gt;&lt;del&gt;SERVER-36248&lt;/del&gt;&lt;/a&gt;, the setup of the sessions sharded collection will not happen until FCV reaches 3.6 and therefore this bug no longer exists.&lt;/p&gt;

&lt;p&gt;Closing as duplicate of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-36248&quot; title=&quot;Do not reject sessions in FCV 3.4&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-36248&quot;&gt;&lt;del&gt;SERVER-36248&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;</comment>
                            <comment id="1979924" author="kaloian.manassiev" created="Mon, 20 Aug 2018 11:48:34 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=misha.tyulenev&quot; class=&quot;user-hover&quot; rel=&quot;misha.tyulenev&quot;&gt;misha.tyulenev&lt;/a&gt;, should this be fixed at the level of the sessions cache to do set-up the &lt;tt&gt;config.system.sessions&lt;/tt&gt; collection at all?&lt;/p&gt;

&lt;p&gt;Alternatively, I think we can fix it in &lt;a href=&quot;https://github.com/mongodb/mongo/blob/2628472127e9f1826e02c665c1d93880a204075e/src/mongo/db/s/shard_server_catalog_cache_loader.cpp#L328&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;ShardServerCatalogCacheLoader::getChunksSince&lt;/tt&gt;&lt;/a&gt; by checking whether the FCV is 3.4, however I think it is more appropriate to do it in the sessions code.&lt;/p&gt;</comment>
