MariaDB is crashing every time with [ERROR] mysqld got signal 6. I tried restarting the system and reinstalled few times with home-brew still I am getting this crash as soon as I connect from my app. Here are the steps.
1. Install mariadb using home-brew
2. Set the root password
3. Connect using MySQLWorkbench with root
4. Create the database with all the tables around 10.
5. Get results by executing few select statements in MySQLWorkbench like select count from information_schema.processlist; SHOW VARIABLES LIKE 'open%'; and show variables like 'max_connections';
6. Run my Scala app from IntelliJ IDEA
7. Now my app hangs or says not able to connect to database server after couple of statements executed. The same code was working fine in the previous mariadb couple of months back.
8. Try executing the above same queries in MySQLWorkbench and it says 'Error Code: 2013. Lost connection to MySQL server during query'

Here is the log file content from /usr/local/var/mysql/xxxxxxx-MacBook-Air.local.err

      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.

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: 10.3.8-MariaDB
key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=12
max_threads=153
thread_count=18
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467396 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...
