Unfortunately, I have not encountered such a problem with Percona. After<br>
the AIO config change I am able to dump Percona server without any hangs.<br>
<br>
Maybe you could try asking on the the CRIU mail list (<a href="mailto:criu@openvz.org">criu@openvz.org</a>)<br>
as I am currently using an outdated CRIU version and may misguide you.<br>
People there are really nice and always happy to help.<br>
