Random WordPress "Errorr Establishing Database Connection" errors, every 1-2 days
My Wordpress website is going offline every 1-2 days, with this error. The site was built using EasyEngine 3.
Looking at the stats, just before this happens I get a jump in Disk I/O reads from virtually 0 MB/s to about 0.89MB/s
Can anyone give me a few tips in order to effectively troubleshoot this, e.g what are the best logs to check (MySQL) etc?
This has been happening for a couple of weeks.
