Does adding the line

```
config_file_version = 2

```

above

```
#########################################
### SERVER CONFIGURATION ###
#########################################

```

in grin-server.toml fix the problem?

I suggest you enable debugging and check if there’s something in the logs as suggested here

I changed `stdout_log_level` and `file_log_level` to `Debug`. I see errors in `grin-server.log`.

I followed [build docs](https://github.com/mimblewimble/grin/blob/master/doc/build.md) in Debian and grin node running without any issues or core dump. I will do the same in Arch installation. The problem remains in v5.1.0. I read in debian wiki that the problem probably caused by older CPUs and avx2 dependency. In my case avx2 is supported.
