We are hosting our server on Linode (4 CPU, 8G RAM, 160G SSD), and we have been running Cyberpanel V2. for almost a year without any issues. Since we upgraded to V2.1, the server started to freeze every 2-3 days, and we have to reboot it to get all sites working again.
Log file show no issues.
Linode support confirmed that there is no issues on the hardware.
We are currently utilizing (35% of hard drive), and CPU is running at 6%, so there is no issue with resources.
The only variable is the Cyberpanel version (v2.1 vs v2)…
I am wondering if anybody is facing this issue, and if you can share a solution.
Please upgrade your cyberpanel installation to the latest as there has been many fixes and security updates done. You can take snapshot backup of the current setup in case anything goes wrong you can restore it back. If everything works pretty fine for you with regards to all the websites hosted with the latest version, continue using the latest as its most recommended.
