Random crash on a fresh installed dedicated server

So basicly, today we got our new dedicated server rented on OVH.com I made a fresh install like we’ve got before but couldn’t have the server up for more than 1h30.

Operating system: Debian 10
Processor: AMD Ryzen 5 3600x
Server: GAME-1 with 64 GO Ram

The issue occure randomly without any lag coming to announce a crash or anything.

I tried increasing the ulimit to unlimited, I updated mono, updated the server, restarted the server.

I changed many times the FXVersion to see if it was caused by this.
First time I was on : Build 2315
Changed to 2289
than changed to 2189
Than back to 2289
Finaly went on the last recommended AKA build 1971

Nothing change still crashing randomly.
I am out of idea I hope one of you has solved this issue in the past or know what is causing that. I’m looking forward to move on Ubuntu might be better for a gameserver ? Could it be a physical issue with the server. I need help :cry:
