                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Customers using continuous backups have observed lengthy stalls on the first checkpoint after the backup. Observed symptoms include a lengthy stall in ftdc, stall in secondaries fetching oplog, resulting in increasing lag and complete stall in writes on the primary due to flow control.&lt;/p&gt;</description>

As part of the PM-1773 performance test along with backup running in the background doesn&apos;t show much overhead on the running system when the backup is running, other than increasing the disk IO usage.&lt;/p&gt;

&lt;p&gt;Closing this ticket as there is no more work to be done in the WT backup.&lt;/p&gt;</comment>
