            <title>[SERVER-13181] cap compact index build heap memory usage</title>
                <link>https://jira.mongodb.org/browse/SERVER-13181</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Running a longevity compact test I realized mongod  memory usage increases all over the time until it eats a quantity of memory &amp;gt;= total available RAM and get kicked out of the scheduling by the OS.&lt;br/&gt;
The following test run continuously in a loop eventually reproduce the behavior described above.&lt;/p&gt;

	&lt;li&gt;Fix leak in buildAnIndex - initiateBulk allocates a BtreeBulk which is never deleted&lt;/li&gt;
	&lt;li&gt;Fix leak in MultiIndexBlock - we are leaking BtreeBulk since we use a raw pointer&lt;/li&gt;
