Buffer overflow detected - mariadb crashing regularly

      Description

      i setup galera cluster for magento2 CE 2.2.6 after setup in run fine but after a minute of 15 it crashed compleet. What happend now is that every 5 til 30min +/- a database crash. When i have bad luck the compleet cluster crashed.
      I looked for a solution the last 2 weeks and i tried to downgrade the database from 10.3.11 till 10.3.10 and now i run 10.3.9 but nothing seems to help.

      i also found out that TMP tables are created by magento2 and could be the issue but i don't understand the error. Also auto_increment i set on 3.

      specs setup:
      2 nodes with 16gb 8 cores centos 7
      1 nodes with 64gb 24 cores centos 7
      mariadb 10.3.9 (all nodes)
      haproxy is running as loadbalancer

      Server version: 10.3.9-MariaDB-log
      key_buffer_size=33554432
      read_buffer_size=2097152
      max_used_connections=25
      max_threads=153
      thread_count=64
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 662852 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      where mysqld died. If you see no messages after this, something went
      terribly wrong...
