&lt;p&gt;Move display of MapReduce results to before the assert test to help debugging.&lt;br/&gt;

&lt;p&gt;Reduce the number of documents inserted per iteration from 100,000&lt;br/&gt;
to 30,000 in jstests/sharding/mrShardedOutput.js when run on a 32-bit&lt;br/&gt;
system.  Do not print the list of inserted documents when the count&lt;br/&gt;
is wrong, just display the documents that are missing.  Add logging&lt;br/&gt;
so we can see where we are in the test if something goes wrong.&lt;br/&gt;

&lt;p&gt;RHEL 32-bit doesn&apos;t give such a clear indication, though it is likely the same problem.  It shows other issues:&lt;/p&gt;
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt; m29000| Sat Nov 17 10:01:32.537 [PeriodicTask::Runner] task: DBConnectionPool-cleaner took: 29ms&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt; m29000| Sat Nov 17 10:26:29.913 [DataFileSync] flushing mmaps took 1514373ms  for 3 files&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;
&lt;p&gt;It&apos;s true: 1514.373 seconds to flush 3 files really is 25 minutes, as shown in the timestamps.&lt;/p&gt;

&lt;p&gt;We may need to pare this test down to make it pass in 32-bit.&lt;/p&gt;</comment>
