            <title>[SERVER-55205] Running shouldStopIteration inline in AsyncTryUntilWithDelay can create deadlock </title>
                <link>https://jira.mongodb.org/browse/SERVER-55205</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;It&apos;s possible for the following to happen:&lt;/p&gt;

&lt;p&gt;1. Service acquires mutex &lt;tt&gt;mx&lt;/tt&gt; and invokes some cleanup work.&lt;br/&gt;
2. As part of cleanup, call &lt;tt&gt;setError&lt;/tt&gt; on owned promises.&lt;br/&gt;
3. AsyncTryUntilWithDelay::runImpl reaches the end of an iteration and invokes &lt;a href=&quot;https://github.com/mongodb/mongo/blob/67ff8452c4172dbbfd2199df2dc349eb739b7bf1/src/mongo/util/future_util.h#L166&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;shouldStopIteration inline&lt;/a&gt;, but shouldStopIteration also acquires &lt;tt&gt;mx&lt;/tt&gt;.&lt;br/&gt;
4. We get a deadlock because the service is unable to finish the cleanup work while holding the mutex, but AsyncTryUntilWithDelay is stuck waiting on the mutex.&lt;/p&gt;</description>
