This is what cPanel said:
Hello,
Thank you for your update. I was able to successfully access the server. I noticed there is a gap in the server logs between roughly 4AM and 10AM server time. I also noticed the following entries in /var/log/messages that appear to be happening directly before each crash:
[11:15:47 server01 root@94536889 ~]cPs# grep fsfreeze /var/log/messagesstyle='font-family:Consolas;color:#2B2E2F;background:#F8F8F8'>

Although this doesn't appear to be related to or caused by cPanel, it appears that another user has opened a bug report regarding a similar issue:
https://gitlab.com/qemu-project/qemu/-/issues/520
In short, it appears that the qemu agent could be causing the kernel to crash when it executes 'fsfreeze'. I would recommend working with your system administrator to temporarily disable this package/function to see if it resolves the issue. Since this package is not managed or developed by cPanel, we would be unable to disable it from our side.
