잘되던거였는데, 서버 재시작 후 mariadb 시작이 안되네요.
구글검색해봐도 알수가 없네요.

/var/log/mariadb/mariadb.log 파일 내용입니다.
혹시 왜그런지 알수 있을 가요?

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 http://kb.askmonty.org/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: 5.5.68-MariaDB

key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=0
max_threads=502
thread_count=0

It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1232387 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
