            <title>[SERVER-14262] Running a compact command on a 2.4 collection in 2.6.1 caused the command to go into a loop and allocate more db files</title>
                <link>https://jira.mongodb.org/browse/SERVER-14262</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;I was running a compact command on a 2.4 collection imported into a 2.6.1 server.&lt;/p&gt;

&lt;p&gt;The collection was ~ &lt;tt&gt;56GiB&lt;/tt&gt; and contained &lt;tt&gt;31&lt;/tt&gt; datafiles originally. &lt;/p&gt;

&lt;p&gt;When I ran compact, the command seems to go into a loop allocating new files datafiles:&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;   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;2014-06-15T15:06:44.997-0400 [FileAllocator] allocating new datafile /data/mongo/dbpath/XXXXXXX.256, filling with zeroes...&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;I stopped the compact command at this point. This was also the second run of compact after resetting the db files (I stopped it at about 100 datafiles on that run).&lt;/p&gt;

&lt;p&gt;Compacting the same collection on a &lt;tt&gt;2.4.10&lt;/tt&gt; instance did not behave this way.&lt;/p&gt;</description>
