Owncloud Sync error lock-unlock files

hosting

#1

I have install Owncloud server v.10.0.2 (install by Softaculous on my webhost in a subdomain)
URL : https://owncloud.ctps.ca
Operating system and version: Cloud Linux (hosting area)
Apache or nginx version: Apache 2.4.27
PHP version 5.6
Windows Owncloud client : 2.3.2

Actually I sometime experiment some locking files error. The only way I manage to solve my problem is to disable the file locking in the config/config.php file witht the line :
'filelocking.enabled' => false,

Source : File is Lock - How to unlock

When the problem is solved after a few sync I deleted the line in the config.php fiile on the server. And the problem do not occur for a few hours...
I only have access to my cPanel on my server to make any correction on the confif.php.

I have note that the Cron service Setting / Admin General / is giving me that message :
Cron : Last cron job execution: 22 hours ago. Something seems wrong.
The little icon (access documentation) send me to a 404 not found error :
So that link is not operational :
https://doc.owncloud.org/server/10.0/admin_manual/configuration_server/background_jobs_configuration.html

Question:
If I want to include here a "Config Report". Is it at: Setting / Admin General / Log / What to Log ???

Log in to the web-UI with an administrator account and click on
'admin' -> 'Generate Config Report' -> 'Download ownCloud config report'
This report includes the config.php settings, the list of activated apps
and other details in a well sanitized form.

So....
Actually I continu to experiment some locking files error. The only way I manage to solve my problem is to disable the file locking in the config/config.php file witht the line :
'filelocking.enabled' => false,

With that line add to my config.php file, the server seems to work perfectly.

Does anyone have a solution for this problem?
