            <title>[SERVER-42468] TransactionCoordinatorMetricsTest has race between transaction coordinator&apos;s lifetime and checking for log lines</title>
                <link>https://jira.mongodb.org/browse/SERVER-42468</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There is a race condition in the &lt;tt&gt;TransactionCoordinatorMetricsTests&lt;/tt&gt; between when we &lt;a href=&quot;https://github.com/mongodb/mongo/blob/ca57a4d640aee04ef373a50b24e79d85f0bb91a0/src/mongo/db/s/transaction_coordinator_test.cpp#L2163&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;stop capturing&lt;/a&gt; the test&apos;s log messages stream and the completion of the asynchronous &lt;a href=&quot;https://github.com/mongodb/mongo/blob/ca57a4d640aee04ef373a50b24e79d85f0bb91a0/src/mongo/db/s/transaction_coordinator.cpp#L397&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;completion&lt;/a&gt; of the transaction coordinator, which might not have gotten to log the slow transaction message by that time.&lt;/p&gt;

&lt;p&gt;In order to fix it, we should wait for the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/ca57a4d640aee04ef373a50b24e79d85f0bb91a0/src/mongo/db/s/transaction_coordinator.h#L108&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;onCompletion&lt;/tt&gt;&lt;/a&gt; notification on the &lt;tt&gt;TransactionCoordinator&lt;/tt&gt; to fire before we stop recording the log messages.&lt;/p&gt;</description>
