Description
Crash with the following backtrace:
Version: '10.4.11-MariaDB-log' socket: '/var/run/mysql/3302.sock' port: 3302 MariaDB Server
|
200122 9:00:00 [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: 10.4.11-MariaDB-log
|
key_buffer_size=17179869184
|
read_buffer_size=131072
|
max_used_connections=158
|
max_threads=2050
|
thread_count=164
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 21288472 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

It was not the case fro the same query and data in older 10.2.x and 10.3.x versions.
