My Cyberpanel VPS time to time going to offline

Hello, dear all,
I have been using CyberPanel for 1 year, and before 3 days, my CyberPanel installed VPS time to time going offline. I checked the error log but could not find an error. Can someone help fix this?

Thank you

what do you see if you run htop command ?

Its showing this

Right now it seems OK. Keep monitoring to see which server process is taking lots of your CPU and then investigate from there.
