This could be caused by: 1) unsupported configuration options combination, please check documentation. 2) a bug in the code. 3) a database corruption. Node consistency compromized, need to abort. Restart the node to resync with cluster. 210622 12:35:02 [ERROR] mysqld got signal 6 ; 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. To report this bug, see https://mariadb.com/kb/en/reporting-bugs We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail.
