            <title>[SERVER-45934] Race in ExhaustCursorUpdatesLastKnownCommittedOpTime integration test</title>
                <link>https://jira.mongodb.org/browse/SERVER-45934</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There is a race between&#160;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/b5134bcb006e74e2102de6e171a28931f84ea12f/src/mongo/db/exhaust_cursor_currentop_integration_test.cpp#L378&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;how the&#160;&lt;tt&gt;curOpMatch&lt;/tt&gt;&#160;was generated&lt;/a&gt;&#160;and &lt;a href=&quot;https://github.com/mongodb/mongo/blob/b5134bcb006e74e2102de6e171a28931f84ea12f/src/mongo/client/dbclient_cursor.cpp#L335&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;the&#160;&lt;tt&gt;queryCursor&lt;/tt&gt; receiving a new batch from getMore&lt;/a&gt;. When the cursor receives a new batch, it sets the cursorId to 0 before parsing the response. So it is possible for the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/b5134bcb006e74e2102de6e171a28931f84ea12f/src/mongo/db/exhaust_cursor_currentop_integration_test.cpp#L378&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;test thread&lt;/a&gt; to race with the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/b5134bcb006e74e2102de6e171a28931f84ea12f/src/mongo/db/exhaust_cursor_currentop_integration_test.cpp#L368&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;queryThread&lt;/tt&gt;&lt;/a&gt; and get a wrong cursorId 0. Therefore, it is possible for a test to use a wrong curOpMatch {command.getMore: 0} in &lt;tt&gt;confirmCurrentOpContents&lt;/tt&gt;, resulting in test failures.&lt;/p&gt;</description>
