Error regarding transactional locking in OwnCloud 10.0.8

As part of a hosting package with the provider All-Inkl I run a private OwnCloud 10.0.8. In the administration section of my OwnCloud I always get the hint to use transactional locking instead of database-based locking.

The documentation states that this feature should be turned on by default and might be blocked by the old file locking app. This is not true in my installation.

Despite some research and inquiry with the provider I did not yet find a solution, how to solve the indicated error. I am grateful for any assistance.

Server configuration

Operating system: Linux 3.13.0-149-generic #199-Ubuntu SMP
Web server: Apache
Database: Mysql 5.6.38
PHP version: 7.1.11
ownCloud version:
Updated from an older ownCloud or fresh install: updated from previous versions


i have installed redis and configured my ownCloud setup on my server following the documentation below. Afterwards the message was gone for me.
