 Description   

Hello,

Galera SST is successfully finishing with error below using mariabackup:

/var/lib/mysql# service mysql start
 
 * Starting MariaDB database server mysqld                                                                                                                                                                                                                                      *** Error in `mariabackup': double free or corruption (out): 0x000055fed20f4920 ***

Can't find anything in the logs.
I can easily reproduce issue in local testing environment.

Don't know if this is a bug or something is wrong with my local environment.

Regards,
Marko

This never happened again - probably the cause has already been fixed some time ago. In addition, MDEV-27524 added changes so that in the event of a failure in the called utilities, SST would never succeed (when we got rc != 0) - this will allow us to catch a similar situation in the future to find the cause.

I suspect it is MDEV-23943, that the beginning of the sst, the innodb memory allocation, ran out of memory and the reuse of innodb code by mariabackup causes the same error.
