            <title>[SERVER-23418] remove_and_bulk_insert.js failing on PowerPC</title>
                <link>https://jira.mongodb.org/browse/SERVER-23418</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The test &lt;tt&gt;concurrency/fsm_workloads/remove_and_bulk_insert.js&lt;/tt&gt; is failing on PowerPC. That test has 5 threads, each doing a mix of bulk inserts and removing all documents in the same collection. The failure is that one of the removes tries to delete a document that is not visible, leading to a &lt;tt&gt;WT_NOTFOUND&lt;/tt&gt;.&lt;/p&gt;

&lt;p&gt;If there was a yield or write conflict between &lt;tt&gt;getNext&lt;/tt&gt; returning a RecordID and the &lt;tt&gt;deleteDocument&lt;/tt&gt; call for that ID, a &lt;tt&gt;WT_NOTFOUND&lt;/tt&gt; from WiredTiger is possible because a concurrent remove could have completed in the meantime. We see lots of write conflicts and yields in this workload.&lt;/p&gt;

&lt;p&gt;Attempts to reproduce on x86 have so far been unsuccessful.&lt;/p&gt;</description>

Mark B. used one to analyze the core dump and it worked well. Can you let me know when? I opened BUILD-1401 for record keeping. &lt;/p&gt;</comment>
