            <title>[SERVER-81241] Range deleter processor must not try reschedule task during service shutdown</title>
                <link>https://jira.mongodb.org/browse/SERVER-81241</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The range deleter service service shutdown procedure is:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/c556d80f28d51179d78b3f6b3f1ffb53b676b0b2/src/mongo/db/s/range_deleter_service.cpp#L495&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Set the state as down&lt;/a&gt;&lt;/li&gt;
	&lt;li&gt;....do some more stuff....&lt;/li&gt;
	&lt;li&gt;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/c556d80f28d51179d78b3f6b3f1ffb53b676b0b2/src/mongo/db/s/range_deleter_service.cpp#L506-L508&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Turn off the range deletions processor&lt;/a&gt;&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;Hence when a range deletion throws &lt;tt&gt;IndexNotFound&lt;/tt&gt; right while the service is stopping (between 1 and 3), it can happen that the processor tries to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c556d80f28d51179d78b3f6b3f1ffb53b676b0b2/src/mongo/db/s/range_deleter_service.cpp#L316-L317&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;reschedule the task&lt;/a&gt; while the state is changing triggering &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c556d80f28d51179d78b3f6b3f1ffb53b676b0b2/src/mongo/db/s/range_deleter_service.cpp#L164&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this invariant&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;The solution is to hold the proper locks when emplacing the range deletion as it happens &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c556d80f28d51179d78b3f6b3f1ffb53b676b0b2/src/mongo/db/s/range_deleter_service.cpp#L590-L591&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt; or to simply change &lt;tt&gt;emplaceRangeDeletions&lt;/tt&gt; to result in a no-op when called while the service is not up.&lt;/p&gt;</description>
