Discovered mariadb was down and found this logging in syslog.
Apache is running mediawiki and wordpress. Could it be a rogue Wordpress plugin?
It looks like apache told linux to kill mariadb - is that right? But it looks like the memory is being eaten up by apache processes.
I've restarted mariadb and all is running smoothly. But obviously it'd be good to nail down what happened.
Lastly, that last few lines of logging from mysql - I thought it must be a relic from a previous failed upgrade, so I reran mysql_upgrade but it still appears. Maybe a red herring?
