Crash information wrote to a log is as following:

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

Attached mariadb configuration and error log files.

Please note that I am not an expert in setting up Galera cluster and trying to learn how to setup. Possible that that I am going in a wrong direction in setting up the cluster. In any case, I do not expect server to crash!
