I’ve tried to add a SMB share to a nextcloud instance with the external storage app, but when I enter the folder on Nextcloud it either keeps loading forever or tells me there are no files. I’ve tried running

> occ files:scan user

But it throws an error about a locked file

I’ve tried to manually remove the lock as described [here](https://help.nextcloud.com/t/file-is-locked-how-to-unlock/1883) but this doesn’t fix it and the lock just gets recreated. I’ve also tried to add the SMB share on another Nextcloud instance as a test and it works without a problem. Both servers are configured the same, so I wonder what happened on the first server and how can I fix it?

Note: both servers have redis caching for locks enabled

Nextcloud version: 14.0.4  
Operating system and version: Ubuntu 16.04  
Apache or nginx version: Apache 2.4.18  
PHP version: 7.0
