[debian-mysql] Bug#989898: MariaDB crashes with "Crash: WSREP: invalid state ROLLED_BACK (FATAL)"

[Galatoulas Emmanuel]

Package: mariadb-server-10.3
Version: 1:10.3.29-0+deb10u1

Upgrading MariaDB to version 10.3.29 (from version 10.3.27)  via the buster-proposed-updates repository we encounter repeatedly the following error, affecting our Galera Clusters (one with 3 nodes and one with 5 nodes, plus the corresponding Maxscale proxy for each) (a more extended log is attached).
