            <title>[SERVER-8195] Observed timeouts don&apos;t correspond to db.serverStatus().cursors.timedOut</title>
                <link>https://jira.mongodb.org/browse/SERVER-8195</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The docs here &lt;a href=&quot;http://docs.mongodb.org/manual/reference/server-status/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://docs.mongodb.org/manual/reference/server-status/&lt;/a&gt; say that cursors.timedOut is &quot;&lt;span class=&quot;error&quot;&gt;&amp;#91;the&amp;#93;&lt;/span&gt; total number of cursors that have timed out since the server process started&quot;, but I can see dozens of MongoCursorTimeoutException errors (php) scroll by without increasing the count. Is it still sampled/unreliable in 2.2.2? &lt;/p&gt;

&lt;p&gt;We have 2 shards of 3 machines each, but only one has a non-zero timedOut value (&amp;lt;10). I will see php report timeouts in bursts of 20-30, for different queries. Can this mean that the timeouts are happening in a way that does not actually hit the server?&lt;/p&gt;</description>

                            <comment id="241824" author="scotthernandez" created="Wed, 16 Jan 2013 21:09:08 +0000"  >&lt;p&gt;Yes, that sounds correct. The server supports no query timeout (what client do is set a socket read/write timeout which is very different and generally bad wrt/server), and the server only cleans up cursors not used in 10 minutes (if the NoTimeout flag was not used during its creation).&lt;/p&gt;</comment>
                            <comment id="241817" author="parkan" created="Wed, 16 Jan 2013 21:02:44 +0000"  >&lt;p&gt;Scott, am I correct in understanding that the serverStatus().cursors.timedOut value counts cursors timed out by the server after 10 minutes of inactivity (and without noTimeout set), while MongoCursorTimeoutException refers to queries closed by the client after $MongoCursor::timeout ms? &lt;/p&gt;

&lt;p&gt;This is an extremely confusing exception name, especially considering that in other drivers the query timeout is a property on the connection (I understand why it can be useful to change the timeout values per cursor, though)&lt;/p&gt;</comment>
                            <comment id="241803" author="scotthernandez" created="Wed, 16 Jan 2013 20:50:21 +0000"  >&lt;p&gt;The cursor timeout exception is on the client (socket read timeout really) and not the same as the server-side timeouts (from unused cursors). The client exception could be better named to make that clear, but the docs are fairly clear this is a read timeout waiting for results from the server: &lt;a href=&quot;http://us1.php.net/manual/en/class.mongocursortimeoutexception.php&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://us1.php.net/manual/en/class.mongocursortimeoutexception.php&lt;/a&gt;&lt;/p&gt;</comment>
