Hello everyone!  
I have forum discourse image=“/base:2.0.20190625-0946”, and it works properly. I wanted to migrate it to a new image=“discourse/base:2.0.20210528-1735”. Trying to install offline with all sources Everything works fine until backup installation, but when I restore backup from the old forum, it causes sudden CPU util which stays there. Attached are screenshots htop and zabbix. Could you advise why this happens?

Have a look in `/sidekiq` are there any jobs running, a big queue, scheduled jobs running or stuck?
