MariaDB process getting killed once a day on fresh CentOS 7 install
Hi guys,
Basically, MariaDB is getting killed randomly once a day, sometimes it lasts for a couple of days and then it goes down. The logs say it's being killed and not restarting. I checked the server load and it is super low, as I am only hosting a couple domains with almost no traffic.
I can restart the service again no problem using "service mariadb start", but eventually it gets killed.
# service mariadb status
Redirecting to /bin/systemctl status mariadb.service

I've been searching for help on how to solve this but so far, no solution has worked and the logs are not saying much.
Any ideas?
Thanks!
MariaDB crashing usually means that your droplet is running out of memory. Do you see any errors in
/var/log/mariadb/mariadb.log?@kamaln7 that was exactly my first thought. However, there is nothing else in the mariadb.log besides "xxx table is marked as crashed and should be repaired" messages and all that I pasted in my original post.
I recently started the service using "mysqld_safe" instead of "service mariadb start" and it hasn't crashed for 24 hours. Does it make any difference?
