I’m looking for an experienced server admin to investigate a problem with the WordPress install on the Ubuntu 14.04 server I have. It’s a 512mb DigitalOcean cloud droplet (VPS). What’s happening is that every few days the MySQL server crashes and requires a full server reboot to get working again. The solution is for the root cause to be fixed, or for some kind of monitoring system to be put in place. I have root access and can provide SSH access.
