            <title>[SERVER-3989] Cannot suppress ClientCursor::yield &quot;warnings&quot; from logs</title>
                <link>https://jira.mongodb.org/browse/SERVER-3989</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We have loglevel set to 0 and quiet mode on, and our logs are still being filled with these &quot;warnings&quot;, its filling up the disk rapidly&lt;/p&gt;

&lt;p&gt;warning: ClientCursor::yield can&apos;t unlock b/c of recursive lock ns&lt;/p&gt;

&lt;p&gt;We use db.eval specifically for the benefit that it locks the db, so my understanding is these warnings are totally normal because of that.&lt;/p&gt;


&lt;p&gt;db.runCommand( &lt;/p&gt;
{ &quot;getParameter&quot; : &quot;*&quot; }
&lt;p&gt; )&lt;br/&gt;
{&lt;br/&gt;
        &quot;quiet&quot; : true,&lt;br/&gt;
        &quot;notablescan&quot; : false,&lt;br/&gt;
        &quot;logLevel&quot; : 0,&lt;br/&gt;
        &quot;syncdelay&quot; : 60,&lt;br/&gt;
        &quot;replApplyBatchSize&quot; : 1,&lt;br/&gt;
        &quot;ok&quot; : 1&lt;br/&gt;

&lt;p&gt;warning: ClientCursor::yield can&apos;t unlock b/c of recursive lock ns&lt;/p&gt;

&lt;p&gt;These log entries are generating 6GB+ daily log files and I don&apos;t have a very busy application, nor do I get alot of traffic.&lt;/p&gt;</comment>

Please open a ticket so we can help diagnose the issue.&lt;/p&gt;</comment>

We have a similar problem where we are locking the db by application design using findAndModify, and it&apos;s very rapidly filling up disk with logs.&lt;/p&gt;</comment>
