Suddenly, after simply adding a few tables to database within the install... the service won't start. Any help welcome.

systemctl start mariadb
Job for mariadb.service failed. See 'systemctl status mariadb.service' and 'journalctl -xn' for details.

The issue is that the system cannot assign any memory to the process to be able to start, you either need to stop some other processes so that memory is free to be allocated to MariaDB or you need to add more RAM or SWAP space to the server so that the processes can start correctly.

  • Thanks for answering. I ended up doubling my ram by moving the site to a larger instance. – Ryan Prentiss Jan 8 '15 at 9:38

    Just read your other comment. I was running on 512MB, but am now up to 1G. Will look to add a swap on top of that for any spikes. – Ryan Prentiss Jan 8 '15 at 9:40
