211022 11:00:36 [ERROR] mysqld got exception 0xc0000005 ;

....

Server version: 10.3.27-MariaDB-log

key_buffer_size=134217728

read_buffer_size=131072

max_used_connections=70

max_threads=65537

thread_count=58

It is possible that mysqld could use up to 

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 137167 K  bytes of memory

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