            <title>[SERVER-52918] Mongos router repeatedly crashes</title>
                <link>https://jira.mongodb.org/browse/SERVER-52918</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Today the mongos router process in our staging environment started crashing repeatedly. If we do not attempt to open any mongo connections via it, it will stay up. But when you try to connect to mongo via it, the connection hangs (eg with the mongo cli you never reach the prompt), and if you terminate the connection (eg ctrl-c the mongo cli) the mongos immediately crashes, with the following messages being logged:&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;Thanks for including the duplicate ticket and providing your fix for the issue. I&apos;ll go ahead and close it as a duplicate of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-47533&quot; title=&quot;rollback_wt_drop.js should wait for reaping before moving on to next phase&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-47533&quot;&gt;&lt;del&gt;SERVER-47533&lt;/del&gt;&lt;/a&gt;.&#160;&lt;/p&gt;

&lt;p&gt;Best,&lt;/p&gt;

                            <comment id="3494466" author="gavin.aiken@netcuras.com" created="Tue, 17 Nov 2020 20:20:42 +0000"  >&lt;p&gt;Sorry, looks like this is a duplicate of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-47553&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/SERVER-47553&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;We found that a restart of our config set fixed the issue with the mongos.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;It also sounds like the issue is fixed in later 4.2.x versions (we have 4.2.6) so we will plan to upgrade ASAP.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;I think this issue can be closed.&lt;/p&gt;</comment>
