Before the error, there are just logs of changes in bodygroups and people talking.

I'm using mtxserv so I don't have full control of the machine. But according to them, their VPS have an AMD Ryzen 5800X and 128 GB of DDR4 ECC 2666 MHz RAM. Since it's a VPS it's shared between several servers.

With jit I saw that it is an x86 server on Linux.

Thank you for helping me.

There's nothing I can do do without the stack trace or at least the core dump and exact server version.
