Description
When i'm trying to perform 'use information_schema' expression, MariaDB-10.3.15 goes down and writes next information to log:
190605 11:57:46 [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: 10.3.15-MariaDB-log
|
key_buffer_size=134217728
|
read_buffer_size=131072
|
max_used_connections=1
|
max_threads=42
|
thread_count=9
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 223386 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
|
where mysqld died. If you see no messages after this, something went

terribly wrong...

And below in log I see that coredump was generated:
Writing a core file...
|
But directory specified in kernel.core_pattern is empty:
sysctl kernel.core_pattern
|
kernel.core_pattern = /var/***/cores/core-%e-%s-%u-%g-%p-%t
|
|
|
ll /var/***/cores/

This problem also can be reproduced with official Docker image:
docker run --name mariadb-10.3.15 -e MYSQL_ROOT_PASSWORD=password -d -p 3333:3306 mariadb:10.3.15-bionic
|
|
|
