Starting about 5 days ago, something has started pinning CPU usage over 100% when it is typically averages under 50%. It is making the site very slow and unresponsive. I've turned off every other website running to narrow it down to IP Board. I'm using Cloudron to manage the sites. If I restart the container running the board, it will get responsive for a short term before it starts to bog down again.
Have done no changes recently to the website or configuration. If I run htop, I can see a mysqld process running at high cpu usage, and it will keep running for days if I don't restart the server. When I log into mysql, I can't see any queries running that match that.
Have had the Cloudron folks take a look at this, and they think it is something with the board software. Can't see anything wrong on their end.
Any thoughts on next steps on this?
