                            <comment id="1129571" author="ramon.fernandez" created="Fri, 8 Jan 2016 13:31:44 +0000"  >&lt;p&gt;Thanks for your report &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=aayushi&quot; class=&quot;user-hover&quot; rel=&quot;aayushi&quot;&gt;aayushi&lt;/a&gt;. Depending on the storage engine, MongoDB 3.0 provides either collection-level or document-level locking.&lt;/p&gt;

&lt;p&gt;Please note that the SERVER project is for reporting bugs or feature suggestions for the MongoDB server.
