Nextcloud version: 22.2.0
Operating system and version: Debian 10 (x64)
Apache or nginx version: Apache/2.4.38 (Debian)
PHP version: 8.0.11
The issue you are facing:
All files uploaded via web or client sync freezes at 100% for about 30sec before showing an “unknown error” (Android: error occured while waiting for the server).
However, the file is actually uploaded and locked for a bit (after a while, file gets unlocked and shows normally in Nextcloud as if nothing happened).
It becomes a bigger problem when uploading multiple files, as they seem to each take a php-fpm child process, crashing the entire apache website if syncing more than 5-10 files “at once” (need to restart php-fpm to access nextcloud again).
Is this the first time you’ve seen this error? (Y/N): Yes
Steps to replicate it:
Unknown, the problem randomly appeared (no NC configuration change) a few weeks after changing from php 7.4 to php 8.0. Due to the delay, I don’t think this is linked.
