Fresh installation NC 18, Changing config - Apache Load at 100% bad response

ℹ️ Support

Nextcloud version 18.01
Operating system and version Debian 10.3 (buster)
Apache or nginx version Apache 2.438
PHP version 7.3

After installing NC 18 freshly on Debian 10 Buster - everything worked very good, but today I ran into a big problem - NC 18 got really slow and Apache Process(es) was running at 100%

I then had to go my configuraiton steps backwards to find out what had caused this - I even looked in this forum, but could only find old topics that were never solved.

I installed libmagickcore-6.q16-6-extra on Debian to get the automatic Favicon-Feature.
After uninstalling libmagickcore-6.q16-6-extra the load went to normal an Nextcloud became really fast again.

What’s the problem here - does anyone have insights?

Protocol in Nextcloud says something like this - might be related:

Any advice is much appreciated.

Interesting: just found out, that the svg I used as a logo cannot be converted using imagick cli-tool - it also get’s stuck at 100% cpu-load … maybe the svg is corrupt or something - just used another svg as a logo and everything is working fine - so not really a nextcloud issue, but still a severe one for servers running nextcloud.
