Nextcloud version : 14.0.3
Operating system and version: Debian 9.5
Apache or nginx version: Nginx 1.10.3
PHP version: 7.0
The issue you are facing:
So yesterday I finally migrated to NC14 after a long time of hesitation. Everything works fine apart from the issue described below.
Whenever I open a folder with photos in it, NC starts to create thumbnails, that’s when CPU usage for php7.0-fpm rises to 100% and remains like that for at least a minute. Navigating webui during this time is extremely slow. On NC13 this was never an issue, the thumbnail creation process appeared to have stopped as soon as I got out of the folder with photos.
I did not find anything related on the board, sorry if similar problem has already been reported.
I’ll be very grateful for any assistance.
Is this the first time you’ve seen this error? (Y/N): Yes
Steps to replicate it:
- Navigate to a folder with photos in it.
- Thumbnail creation starts.
- CPU at 100% for a minute or so, everything gets back to normal shortly after. Situation repeats itself every single time.

Might be worth adding that I have NC set up on openmediavault installation (4.1.12). Issue occurs with NC only, omv webgui does not cause any hiccups whatsoever.
