Appwrite mariadb container suddenly using 99% of cpu and memory

I'm hosting an instance of appwrite since months and updated to 1.8.0 couple of weeks ago. Everything worked fine, but today I noticed that my server is lagging very much. Checking the system I see that the appwrite mariadb container is using 99% of cpu and memory. Even after restart. Nothing besides me is using the server or the appwrite instance. It's just some basic projects I'm working on but really really small. I'm using appwrite for a while now and never noticed something like this. I also don't thing is directly connected to updating to version 1.8.0. Any idea what to do about it?
