            <title>[SERVER-10012] Segmentation fault on splitChunk</title>
                <link>https://jira.mongodb.org/browse/SERVER-10012</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We use a mongodb sharded setup with four shards (each a replicaset with one two mongodbs and one arbiter). Since we do batch inserts we use pre-splitting. All mongodbs are version 2.4.3.&lt;/p&gt;

&lt;p&gt;One the slave of one of the shards we got the following segmentation fault:&lt;/p&gt;

&lt;p&gt;The database is running fine for some time after we restart it. After a few hours the segmentation fault occurs again. We already tried removing the dbpath files and letting the mongodb do an initial sync (this occasionally succeeds but the segmentation fault happens again).&lt;/p&gt;</description>

&lt;p&gt;Apologies for the delay in follow-up on this issue. Your last response suggested that you had found a workaround using splitChunk from a single &lt;tt&gt;mongos&lt;/tt&gt;, and we did not have any additional logs to review.&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-7790&quot; title=&quot;Segfault in splitchunk following dropDatabase&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-7790&quot;&gt;&lt;del&gt;SERVER-7790&lt;/del&gt;&lt;/a&gt; which you mentioned does seem to be a similar issue, and the feature requests &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-4537&quot; title=&quot;better protect all sharding admin operations from simultaneous commands&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-4537&quot;&gt;&lt;del&gt;SERVER-4537&lt;/del&gt;&lt;/a&gt; and &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-5160&quot; title=&quot;Handle all failed shardCollection commands well&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-5160&quot;&gt;&lt;del&gt;SERVER-5160&lt;/del&gt;&lt;/a&gt; may also be relevant for you to watch &amp;amp; upvvote.&lt;/p&gt;

&lt;p&gt;FYI, in MongoDB 2.4.8+ there is now caching for dbhash results which should improve performance using multiple mongos: &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-11021&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/SERVER-11021&lt;/a&gt;. If you have a large config database and multiple mongos, it&apos;s possible that long-running dbhash commands could have contributed to slowness and spurious &quot;config servers differ&quot; warnings.&lt;/p&gt;

&lt;p&gt;I&apos;m going to close this issue, but please feel free to reopen if you have new information to investigate.&lt;/p&gt;

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

&lt;p&gt;sorry for not replying earlier, I was on vacation.&lt;/p&gt;

&lt;p&gt;1. The change we made was to limit the splitChunk commands to one&lt;br/&gt;
application. Beforehand we had multiple servers, each with an application&lt;br/&gt;
and a mongos. Each application created collections in a sharded database,&lt;br/&gt;
sharded these collections and did splitChunk commands to do pre-splitting&lt;br/&gt;
before doing mass inserts. After the change we only had one application&lt;br/&gt;
creating, sharding and splitting the collections (and putting the&lt;br/&gt;
collections in a collection pool). The actual executed commands did not&lt;br/&gt;
change. I assume that not doing createCollection, shardCollection and&lt;br/&gt;
splitChunk in parallel massively fixed our problem with the segmentation&lt;br/&gt;
fault.&lt;/p&gt;

&lt;p&gt;2. It is possible that single mongos did not run exactly the same version&lt;br/&gt;
but if so it was very close (like mainly 2.4.3 and one or two 2.4.2).&lt;/p&gt;

&lt;p&gt;3. The &quot;config servers x and y differ&quot; messages occured all over the place&lt;br/&gt;
(every other minute for hours). This problem reappeared even after we&lt;br/&gt;
manually re-synced the config servers (several times) and restarted the&lt;br/&gt;
mongos instances. This was another reason we limited the creating,&lt;br/&gt;
sharding and splitting of the collections to one application since this&lt;br/&gt;
also fixed the config server problem.&lt;/p&gt;

&lt;p&gt;4. I am not sure if we still have mongos logs from the time of the&lt;br/&gt;
segmentation fault since this was quite some time ago but I will look. It&lt;br/&gt;
will probably be hard to find the right mongos since we had like 6 or 7 of&lt;br/&gt;
them and only one would have issued the problematic splitChunk command.&lt;/p&gt;

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

&lt;p&gt;To help us diagnose the issue, I have few questions:&lt;/p&gt;

&lt;p&gt;1. What exactly do you mean by &quot;if we only did the splitChunk from one mongos&quot;?  What were the exact split commands you were running before and after this change, and from what arrangement of mongos&apos;s?&lt;br/&gt;
2. Can you confirm that all of the mongos&apos;s are running the same version?&lt;br/&gt;
3. The &quot;config servers x and y differ&quot; line indicates that the data is not consistent across the config servers.  Did these errors occur before or after the segmentation fault?&lt;br/&gt;
4. Would it be possible to post logs from one or more of the mongos&apos;s from the time that the issue occurred?&lt;/p&gt;

&lt;p&gt;Thank you&lt;/p&gt;</comment>
                            <comment id="379602" author="blaine" created="Fri, 12 Jul 2013 07:54:10 +0000"  >&lt;p&gt;We tracked this down a bit. We had a number of mongos running on the sharded setup and we did not get the segmentation fault any longer if we only did the splitChunk from one mongos (one application using this mongos). Maybe this is related to &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-4537&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/SERVER-4537&lt;/a&gt; or &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-7790&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/SERVER-7790&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Also one additional note: I dont know if this is connected but while we were having this problem we also encountered problems with our config servers. The config servers continued to run but the mongos instances had many &quot;config servers x and y differ&quot; lines in the logs.&lt;/p&gt;</comment>
