Hi Kenneth,

> Do you have ideas on what is causing "InnoDB: Failed to set memory to DODUMP: Invalid argument ptr .. " warning?

The message that you are seeing is due to
MDEV-10814: Innodb large allocations - madvise - Don't dump
https://jira.mariadb.org/browse/MDEV-10814

I have informed the contributor about this.
