I moved one Fusion PBX server to another.
The destination server crashes every few days or less and does not come back without a restart. And it is not possible to connect via ssh when the server is down.
And in my opinion, this is a problem in Linux and not in the aforementioned application.
The operating system is CentOS 7
If you know the problem and know how to solve it - please contact me.
I am attaching a picture of the console when the server is down
