Initializing database

PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following commands:
2019-03-11T16:01:39.424553372Z 
'/usr/bin/mysqladmin' -u root password 'new-password'
'/usr/bin/mysqladmin' -u root -h  password 'new-password'
2019-03-11T16:01:39.424567558Z 
Alternatively you can run:
'/usr/bin/mysql_secure_installation'
2019-03-11T16:01:39.424581734Z 
which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

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.
2019-03-12T08:39:34.961749049Z 
Server version: 10.4.3-MariaDB-1:10.4.3+maria~bionic
key_buffer_size=134217728
read_buffer_size=2097152
max_used_connections=1
max_threads=102
thread_count=7
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 760202 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
