            <title>[GODRIVER-2917] Aggregation cursor timeouts cause the cursor to stop iteration with no error reported</title>
                <link>https://jira.mongodb.org/browse/GODRIVER-2917</link>
                <project id="14289" key="GODRIVER">Go Driver</project>
                    <description>&lt;p&gt;Note: This is affecting the BI Connector so the fix will need to be backported.&lt;/p&gt;

&lt;p&gt;Included are my go and python programs that illustrate the difference in behavior.&lt;/p&gt;

&lt;p&gt;I have created a collection in test named tenkdocs. Just make sure it contains 10k docs (really, more than 100 is fine, since that is where both the python and go driver stop).&lt;/p&gt;

&lt;p&gt;Start mongod with the following parameters:&lt;br/&gt;
 `--setParameter internalDocumentSourceCursorBatchSizeBytes=1 --setParameter cursorTimeoutMillis=2000 --setParameter  clientCursorMonitorFrequencySecs=1 --setParameter enableTimeoutOfInactiveSessionCursors=true`&lt;/p&gt;

&lt;p&gt;As the title hints, the python program raises a CursorNotFoundError, while the go program reports no error, resulting in users thinking there are fewer results than there are.&lt;/p&gt;</description>
