            <title>[SERVER-7003] Deletions during chunk movement can cause migrations to fail</title>
                <link>https://jira.mongodb.org/browse/SERVER-7003</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;If, while a chunk migration is in progress, objects inside of the chunk that&apos;s being moved are deleted on the donor shard, then the receiver shard can prematurely abort the migration, giving errors that look like:&lt;/p&gt;
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;Assertion: 16333:field names of bound { _id: ObjectId(&apos;5139739ec9b413112c01414b&apos;) } do not match those of keyPattern { a : 1.0 }&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;
&lt;p&gt;This does not compromise data, but prevents migrations from finishing, and impacts performance. &lt;/p&gt;</description>
