                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;hi&lt;/p&gt;

&lt;p&gt;&#160; &#160; we have a problem when we send query same litter data collections in secondary always appear same very slowly query problems ,every day about one or two times.in the slowly logs we could find the&#160;timeAcquiringMicros take the longest time in the query.i think if always appear this problem .maybe we can&apos;t use secondary as one of the query point for share the responsibility of primary .because this will block&#160; the query too long time.and let our program became dead.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;the log like this&#160;&lt;/p&gt;
&lt;p/&gt;

Alternatively, you can upload all the data to this &lt;a href=&quot;https://10gen-httpsupload.s3.amazonaws.com/upload_forms/34bf9fe2-4d81-43b7-9d01-3324102644ef.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;support uploader&lt;/a&gt; location.&lt;/p&gt;</comment>
