CPU Spikes - cant explain?!

Nextcloud Hub 8 - 29.0.2 - Docker Installation
8 Cores - 32GB RAM

From time to time we have strong performance fluctuations, thanks to the monitoring I have noticed the extreme CPU spikes. But I can’t explain what triggers them. Can someone help me and tell me where I can look for the cause?

Make an ssh connection and start a tool like htop to see the process when load increases.

an extract from just now, why so high php-fpm usage?!
