                            <comment id="1389910" author="wxiaoguang@gmail.com" created="Wed, 21 Sep 2016 16:09:58 +0000"  >&lt;p&gt;Thanks for your quick response and fix.&lt;/p&gt;

&lt;p&gt;We decided to disable &quot;move chunk&quot; and &quot;auto split&quot; in our production environment because we have experienced the mongo cluster no-response problem at least 3 times recently, we are sure these problems are caused by &quot;move chunk&quot; and &quot;auto split&quot; with high workload.&lt;/p&gt;

&lt;p&gt;And, this crash(&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-26159&quot; title=&quot;mongos crashes:  Invariant failure !op-&amp;gt;timedOut() src/mongo/executor/network_interface_asio.cpp&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-26159&quot;&gt;&lt;del&gt;SERVER-26159&lt;/del&gt;&lt;/a&gt;) only occurs when auto splitting with high workload which causes the mongos instances can not connect to mongod. (Unfortunately, we don&apos;t have chance to enable auto splitting in our production environment because we have to keep our service stable recently.)&lt;/p&gt;

&lt;p&gt;It is suspected that the design of &quot;chunk&quot; has defects. Can you look into the &quot;move chunk&quot; and &quot;auto split&quot; procedure to prevent mongo cluster stopping response under high workload? &lt;/p&gt;</comment>
                            <comment id="1389866" author="samantha.ritter@10gen.com" created="Wed, 21 Sep 2016 15:42:59 +0000"  >&lt;p&gt;Hi &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=wxiaoguang%40gmail.com&quot; class=&quot;user-hover&quot; rel=&quot;wxiaoguang@gmail.com&quot;&gt;wxiaoguang@gmail.com&lt;/a&gt;,&lt;/p&gt;

&lt;p&gt;Thank you very much for the information and log files.  I have found a race condition in our connection code.  The race is triggered when communication between cluster members takes about as long as our timeout value, so it makes sense that you encountered it when mongos was stuck trying to refresh.  I&apos;m very sorry that this bug has been interfering with your service, especially after &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-25465&quot; title=&quot;Mongos crashing due to segmentation error.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-25465&quot;&gt;&lt;del&gt;SERVER-25465&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;I&apos;ve merged in the fix for this race condition to both our v3.2 and master branches.  This fix will be available in 3.2.10-rc1, which we will release shortly.  If you are willing to upgrade to rc1 when it comes out, we are hopeful that it will fix this issue for you.  If rc1 does not fix the issue this will continue to be a top priority for us.&lt;/p&gt;

&lt;p&gt;I&apos;m going to resolve this ticket.  If you continue to see this issue in 3.2.10-rc1, please don&apos;t hesitate to open a new ticket so we can address the problem right away.&lt;/p&gt;

&lt;p&gt;Thanks,&lt;br/&gt;

&lt;p&gt;Thank you for answering Sam&apos;s questions. Please be aware that I&apos;ve moved the uploaded files to the secure upload portal that she provided.&lt;/p&gt;

&lt;p&gt;Kind regards,&lt;br/&gt;

5 mongos instances&lt;br/&gt;
5 shards (1 primary, 2 repl, 2 arbitrary for every shard)&lt;br/&gt;
3 config instances (1 primary, 2 secondary)&lt;br/&gt;
all: WT engine, XFS file system&lt;/p&gt;

Almost every time when the server is busy.&lt;br/&gt;
Especially when the mongos crashed, even if we restarted it again, it would crash soon because too many incoming requests.&lt;br/&gt;
Our service is down for 2 hours because this bug. We even couldn&apos;t not make the mongos running.&lt;/p&gt;

&lt;p&gt;&amp;gt; Is it something you are able to reproduce consistently?&lt;br/&gt;
&amp;gt; If so, what sort of workload are you running when you encounter the bug?&lt;br/&gt;
I think a related case is mongos is doing auto-splitting.&lt;br/&gt;
It caused the config information not synced between mongos instances.&lt;br/&gt;
When the mongos instances are trying to refresh config information, the mongos blocks, and timeout occurs.&lt;br/&gt;
Yesterday we disabled auto-splitting of mongos, there is no crash again.&lt;/p&gt;

&lt;p&gt;&amp;gt; Would you please upload an archive of the diagnostic.data directory from the dbpath of a primary node?&lt;br/&gt;
&amp;gt; Are you running a replica set or a sharded cluster? How many nodes?&lt;br/&gt;
&amp;gt; Would you please upload the complete logs from the crashed server?&lt;br/&gt;
I will ask our DBA.&lt;/p&gt;
