<br>
Since I upgraded my CT from Debian Jessie to Debian Stretch (9.3), I<br>
cannot online migrate it anymore. I figured out that the issue only<br>
appears while the CT is running mariadb-server (10.1). When I suspend<br>
the CT while mariadb is running, I get the following errors when I try<br>
to restore:<br>
<br>

When mariadb server is stopped, I can normally suspend and restore the<br>
CT.<br>

<br>
This is with:<br>
<br>
* Debian wheezy hostnode running:<br>
* OpenVZ kernel: 2.6.32-openvz-<wbr>042stab127.2-amd64<br>
* Debian Stretch CT<br>
* mariadb 10.1.26<br>
<br>
Thanks,<br>
