Other nodes remained synched, I could restart this node with a simple sudo systemctl start mariadb.

What MariaDB version? How can we repeat this issue?

Comment by COUNOTTE CEDRIC [ 2023-05-23 ]

Version is 10.6.x (x upto 12).

I believe that crash was related to this bug report: MDEV-26298

I've configured the mentioned workaround and had no crash so far:

wsrep_provider_options = "cert.optimistic_pa = no"

Now I've upgraded one of our cluster to 10.6.13 and each time I restart a node being a replication slave of the other cluster, it keeps crashing until I restart the whole cluster which causes a SST re-sync of the 2 other nodes of the cluster. Too busy to open a bug report atm.
