Reported upstream as: https://jira.mariadb.org/browse/MDEV-20505 -- It seems that, when properly configured, the issue is not triggered. Rawhide just recieved the 10.4.11 release. The issue is fixed there by setting "wsrep_on=0" by default, so user must enable it before using it. |
The MariaDB 10.4.6 module crashes with a coredump, when trying to use replication. When "mariadb-galera" package is installed, it will add a "/etc/my.cnf.d/galera.cnf" configuration file with option "wsrep_on=1". In that case, the start of the mysqld daemon (e.g. by "systemctl start mariadb") will fail with a coredump. -- Workarounds: 1) do not install "mariadb-galera" package 2) set "wsrep_on=0" in your cofiguration, do not use replication. ----------------------------------------- # coredumpctl -1 dump PID: 26621 (mysqld) UID: 27 (mysql) GID: 27 (mysql) Signal: 11 (SEGV) Timestamp: Wed 2019-06-26 12:19:33 EDT (2min 34s ago) Command Line: /usr/libexec/mysqld --basedir=/usr Executable: /usr/libexec/mysqld Control Group: /system.slice/mariadb.service Unit: mariadb.service Slice: system.slice Boot ID: d5dbb8d483244fb7b56054e42b85223b Machine ID: 78722d4a61d145e9af550b0781bbf998 Hostname: host-10-0-137-33 Storage: /var/lib/systemd/coredump/core.mysqld.27.d5dbb8d483244fb7b56054e42b85223b.26621.1561565973000000.lz4 Message: Process 26621 (mysqld) of user 27 dumped core.
