                <link>https://jira.mongodb.org/browse/SERVER-9209</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Mongod crashes with a signal 11 (Segmentation fault) while running a map/reduce job. &lt;/p&gt;

&lt;p&gt;We have 2 nodes in replica with an arbiter. The first node crashed yesterday 19:30 and the second node took over, just like it should. &lt;/p&gt;

&lt;p&gt;Unfortunately the second node crashed as well at 06:35 this morning. &lt;/p&gt;

&lt;p&gt;Here are the stacktraces and errors:&lt;/p&gt;

&lt;p&gt;;&lt;br/&gt;
        values.forEach(function(value){&lt;br/&gt;
          if (value.date) &lt;/p&gt;
{
            result.count += value.count;
            result.dates.push(value.date.valueOf());
            result.ids.push(value.id)
          }
&lt;p&gt;        });&lt;br/&gt;
        return result;&lt;br/&gt;

    }&lt;/p&gt;

&lt;p&gt; else &lt;/p&gt;

      }&lt;br/&gt;
    }&lt;/p&gt;

&lt;p&gt;It will happen once every 4 out of 10 times. Also it happens when I use the mongo shell as well as the mongo ruby driver as well as mongoid which uses the moped driver.&lt;/p&gt;

&lt;p&gt;Here is my mongo.conf&lt;/p&gt;

&lt;ol&gt;
	&lt;li&gt;Store data in /usr/local/var/mongodb instead of the default /data/db&lt;br/&gt;
dbpath = /usr/local/var/mongodb&lt;br/&gt;
port = 27017&lt;/li&gt;
	&lt;li&gt;Only accept local connections&lt;br/&gt;
bind_ip = 127.0.0.1&lt;br/&gt;
journal = true&lt;br/&gt;
smallfiles = true&lt;br/&gt;
rest = true&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Unfortunately I can&apos;t post the stack or log but it was doing just some regular inserts and updates, nothing special and no map/reduce. Version was 2.4.1 when crashed, now it is 2.4.3, I&apos;ll get back if this one crashes too. &lt;/p&gt;

&lt;p&gt;P.S. We use SSH tunnels to link all the replica members.&lt;/p&gt;

&lt;p&gt;Can you post the stack trace from your crash, with a few dozen lines from before the crash for context (i.e. what was going on when the crash happened), please?&lt;/p&gt;

&lt;p&gt;Alternatively, could you attach the log file?&lt;/p&gt;

&lt;p&gt;What version of MongoDB are you running?&lt;/p&gt;

                            <comment id="328697" author="sologub" created="Sun, 5 May 2013 08:49:52 +0000"  >&lt;p&gt;Got this error too on our production server, but we use no map/reduce at all. We have 5 nodes in replica, two of which are hidden and usually down. The error has been thrown by a secondary member.&lt;/p&gt;</comment>

&lt;p&gt;Could you attach a few additional pieces of information?&lt;/p&gt;

&lt;ol&gt;
	&lt;li&gt;The MapReduce script and command used to execute the script&lt;/li&gt;
	&lt;li&gt;Logs that start from the time the MapReduce job began through the crash&lt;/li&gt;
	&lt;li&gt;A dump of the dataset used for this MapReduce job&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;For the dump, if you could use the &lt;a href=&quot;http://docs.mongodb.org/manual/reference/mongodump/#cmdoption-mongodump--query&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mongodump command with the query specifier&lt;/a&gt; used in the MapReduce jobs, that would be extremely helpful.  If this data is sensitive, I would be happy to provide a secure SCP server you can upload to.&lt;/p&gt;</comment>

&lt;p&gt;We run the same mapreduce job with the same data on another host that runs mongo 2.2.3 and has no issues at all. &lt;/p&gt;</comment>
