            <title>[SERVER-14342] Shard crashes on split operation if collection doesn&apos;t exist on that shard</title>
                <link>https://jira.mongodb.org/browse/SERVER-14342</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;div class=&quot;panel&quot; style=&quot;background-color: #EEEEEE;border-color: #ccc;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;border-bottom-color: #ccc;background-color: #6CB33F;&quot;&gt;&lt;b&gt;Issue Status as of Aug 21, 2014&lt;/b&gt;&lt;/div&gt;&lt;div class=&quot;panelContent&quot; style=&quot;background-color: #EEEEEE;&quot;&gt;
&lt;p&gt;&lt;b&gt;ISSUE SUMMARY&lt;/b&gt;&lt;br/&gt;
On a sharded cluster, a shard may crash when a &lt;tt&gt;splitChunkCommand&lt;/tt&gt; operation is issued on a non-existing namespace. One way to reproduce this is to connect to a shard, drop a sharded collection and then issue the split command through &lt;tt&gt;mongos&lt;/tt&gt; on that collection.&lt;/p&gt;

&lt;p&gt;Non-sharded systems are not affected by this issue.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;USER IMPACT&lt;/b&gt;&lt;br/&gt;
The shard where the namespace doesn&apos;t exist logs a stack trace in the log and crashes. &lt;/p&gt;

&lt;p&gt;&lt;b&gt;WORKAROUNDS&lt;/b&gt;&lt;br/&gt;
N/A&lt;/p&gt;

&lt;p&gt;&lt;b&gt;AFFECTED VERSIONS&lt;/b&gt;&lt;br/&gt;
MongoDB 2.4 production releases up to 2.4.10 are affected by this issue.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;FIX VERSION&lt;/b&gt;&lt;br/&gt;
The fix is included in the 2.4.11 production release.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;RESOLUTION DETAILS&lt;/b&gt;&lt;br/&gt;
Do not perform any split operations if the namespace doesn&apos;t exist on a given shard.&lt;/p&gt;
&lt;/div&gt;&lt;/div&gt;
