&lt;p&gt;We haven&apos;t heard back from you and don&apos;t have enough information to diagnose this further, so I&apos;ll go ahead and close this ticket now. If this is still an issue please feel free to reopen the ticket again and provide additional information.&lt;/p&gt;

&lt;p&gt;Thanks,&lt;br/&gt;

&lt;p&gt;After the &quot;final reduce to collection&quot; message is displayed the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/v2.4/src/mongo/db/commands/mr.cpp#L867&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;remaining steps&lt;/a&gt; are to:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;iterate over all sorted objects&lt;/li&gt;
	&lt;li&gt;apply finalize() function, if defined&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Does your Map/Reduce job include a &lt;a href=&quot;http://docs.mongodb.org/manual/reference/command/mapReduce/#mapreduce-finalize-cmd&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;finalize()&lt;/tt&gt; function&lt;/a&gt;?&lt;/p&gt;

&lt;p&gt;If you have other write operations on the same database, it&apos;s also possible that your Map/Reduce job is yielding. You can check this using &lt;a href=&quot;http://docs.mongodb.org/manual/reference/method/db.currentOp/#db.currentOp&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;db.currentOp()&lt;/tt&gt;&lt;/a&gt; and the &lt;tt&gt;numYields&lt;/tt&gt; value for your Map/Reduce operation.&lt;/p&gt;

&lt;p&gt;Regards,&lt;br/&gt;
