GDB backtrace:
Server version: 11.4.1-MariaDB-1:11.4.1+maria~ubu2204 source revision: fa69b085b10f19a3a8b6e7adab27c104924333ae

|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 468064 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.
