mysqld got signal 11 while executing SELECT statement on information_schema.* tables.

200423 15:18:49 [ERROR] mysqld got signal 11 ;

This could be because you hit a bug. It is also possible that this binary

or one of the libraries it was linked against is corrupt, improperly built,

or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help

diagnose the problem, but since we have already crashed, 

something is definitely wrong and this may fail.

Server version: 10.1.34-MariaDB

key_buffer_size=33554432

read_buffer_size=262144

max_used_connections=249

max_threads=2002

thread_count=160

It is possible that mysqld could use up to 

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1611965 K  bytes of memory

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