I use an external tool to keep an eye on my site and the past week, I've noticed site outages lasting an hour or more each time (including another one today)
The only way I've managed to 'cure' the outages on my site is to restart the MySQL service (rebooting the web PS doesn't seem to fix the problem, so there seems to be a problem database side.).
I'd rather not have to manually keep such a close eye on things (especially in the middle of the night), so it would be nice to be able to automate the monitoring and recovery. It's frustrating knowing that a solution is available, but not being able to do anything about it.
