Description
The mariadb service enrolled in windows service keeps shutting down after "SELECT" statement is executed. I'm deploying SPRING project and this project is based on MariaDB 10.10.2.
This issue pops out intermittently and is not bound to certain SELECT statements. It occurs at random time at random SELECT statement in the project I'm deploying.
I've checked CPU and ram usage as well but no particular sign of overusage of hardware resources.
Originally I was using 10.8 version of MariaDB and that kept shutting down as well. So I decided to use 10.10.2 instead, only to find out the same issue coming out again. As time goes after reinstallation, the crash occurs more often and I'm unable to maintain the service normally.
_*Below is the entire error log.

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: 10.10.2-MariaDB

key_buffer_size=134217728
|
read_buffer_size=131072
|
max_used_connections=42
|
max_threads=65537
|
thread_count=27
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 142742942 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...
