"Delete all files?" Message randomly



Hi Everyone,

i am providing an ownCloud infrastructure for ~800 users. Some users complaining about a "Remove all files?" message, when starting the ownCloud Sync-Client. It appears randomly across all types of operating systems (Linux,Windows,Mac)

Some users tell me, they are starting the Sync-Client and the message appears. Some users get it once, some get this message twice.

Iam figuring out how to reproduce this behavior but i have no clue right now.

Client configuration
Client version: 2.3.1

Server configuration
Operating system: RHEL 7.2
Web server: Apache
Database: Postgresql 9.3.13
PHP version: 7.0.16
ownCloud version: 9.1.4

ownCloud log (data/owncloud.log)

Unfortunately, there is no error or special things in the server logs which are pointing to the problem.

Any thoughts?

Thank you & Have a nice Weekend


What storage are you using? Any connection issues there?



thanks for your reply. I am using a Storage System called dCache. The storage is mounted over NFS 4.1.

I don't see any connection issues there but it is noticeable that users with multiple sync-clients on different devices get this message randomly (even without changes within the folder sync directory).
