            <title>[SERVER-3961] Segmentation Fault when creating new indexes</title>
                <link>https://jira.mongodb.org/browse/SERVER-3961</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Using a sharded cluster consisting of 5 shards. The collection started off empty and using a batch process to load the data from MySQL into Mongo using Mongoid.&lt;/p&gt;

&lt;p&gt;During the run we decided to create multiple indexes to reduce CPU utilization. When creating the indexes the primary server in the first shard crashed with a Segmentation fault. After restarting the mongod we then re-ran the steps to create the indexes, but this time included the background: true option. The second time around it took about a minute and only then crashed with a Segmentation fault. The key is that these collections were queried and inserted into while the indexes were being created. Did not see this problem when running 1.8.3.&lt;/p&gt;

&lt;p&gt;Below are both stack traces from the log file. The first was without the background option and mongod crashed almost immediately:&lt;/p&gt;

We are using the official 10gen 64bit ubuntu packages.&lt;/p&gt;</comment>

We just repackaged the binaries into new RPM files to match: &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-3748&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/SERVER-3748&lt;/a&gt;&lt;br/&gt;
