            <title>[SERVER-31787] Certain aggregation commands with merging on mongos can leak cursors on mongod</title>
                <link>https://jira.mongodb.org/browse/SERVER-31787</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;This was originally found by running the bestbuy aggregation workload against a sharded cluster (see attached BF ticket), but also reproduces with a local setup outside of DSI. The consistently reproducing test case does the following:&lt;/p&gt;

&lt;p&gt;1. Setup 3-node sharded cluster with a single mongos&lt;br/&gt;
2. Presplit the data according to what is done &lt;a href=&quot;https://github.com/10gen/dsi/blob/master/configurations/test_control/test_control.agg_query_comparison_bestbuy.yml&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;&lt;br/&gt;
2. Shard the collection and move chunks to ensure each shard has at least one chunk&lt;br/&gt;
3. Insert 200 documents (exact number probably doesn&apos;t matter) near each split point&lt;br/&gt;
4. Run an aggregate command with the following pipeline: &lt;tt&gt;&lt;span class=&quot;error&quot;&gt;&amp;#91;{$match: {type: &amp;quot;Music&amp;quot;}}, {$limit: 100}&amp;#93;&lt;/span&gt;&lt;/tt&gt; in a loop&lt;/p&gt;

&lt;p&gt;The cursor leak typically occurs within 30 seconds of starting the test.  It&apos;s important to note that the issue does not reproduce when setting the parameter &lt;tt&gt;internalQueryProhibitMergingOnMongoS&lt;/tt&gt;, thus indicating that it appears to be a regression related to aggregation&apos;s merging on mongos.&lt;/p&gt;</description>
