I have these Error once or twice the day in my error log. I don’t have a clue where it comes from. My Nextcloud is running and It seems like all devices sync it’s data. i have no clue if there is really an impact. Anyway it is a fatal error and maybe there fore I want to find the culprit.
[/details]
Nextcloud version (eg, 20.0.5): 21.0.1
Operating system and version (eg, Ubuntu 20.04): Ubuntu 20.04
Apache or nginx version (eg, Apache 2.4.25): nginx 1.17
PHP version (eg, 7.4): 7.4
The issue you are facing:
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
Can’t say. I have the Nextcloud server freshly installed since three days. After setting all things up, I recognized this error in the Logs. I haven’t found out, when it really occurs. The connected devices sync every 30 Minutes. But the error occurs only once or twice a day. I also haven’t recognized, that data wasn’t synced.
