I have an Extra Small instance running CentOS, Apache, and MySQL for WordPress. It's not a live site yet because I'm still testing.
I've noticed that after a period of time - so far just 24-36 hours - the VM hangs. At that point the site times out and I can't get an SSH connection. The only way I can get back in is to force power-down the VM to reboot it. From that point everything starts up and runs fine again.
Any ideas on where to look as to why this is hanging?
