Any suggestions on how to fix this?

About every hour we are getting huge spikes in CPU usage - any idea why?

I normally upgrade my instance using ansible and it all goes smoothly. There is more to this upgrade and I do not understand some of the instructions. I think I need more specifics.

This is what I have done so far:

• Went to https://github.com/LemmyNet/lemmy-ansible
• Run Git Pull as instructed
• Gone to https://github.com/LemmyNet/lemmy/blob/main/RELEASES.md

As I will probably have more then 1 question as I progress through - I will put the questions in different comments.

What are the recommended specs, dimensions,etc for the icon and banner we create for a new instance?
