I upgrade grin node but I keep receiving error message in Arch and Debian.
$ grin
Illegal instruction (core dumped)

Does adding the line

config_file_version = 2

above

#########################################
### SERVER CONFIGURATION              ###
#########################################

in grin-server.toml fix the problem?

The line already exist. No change.

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 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.

Latest release v5.1.0-test3 works without any problem. Thank you
