Description
**Reported in Launchpad by Valerii Kravchuk last update 18-07-2017 10:02:43
The following simple test performed on idle (no connections) almost "empty" instance of MariaDB 10.2.7 started with all defaults but port and datadir shows the problem:

Please report a bug at https://bugs.launchpad.net/percona-xtrabackup
[email protected]:~$
The problem is repeatable with 10.2.6, but is not repeatable with Percona Server 5.7.x or MariaDB 10.1.x.
Without these options everything works as expected:
