            Do you know any other already reported bug that may apply to 10.3.23 and lead to this kind of crash:

            Server version: 10.3.23-MariaDB-log

            thread_count=111
            		 
            It is possible that mysqld could use up to

            Hope that's ok; if not, decrease some variables in the equation.
