use htop and see your memory usage

post free -m resutls at the time you can't open... May be you are running out of memory ?

What's your VPS specification ?? and OS ?

pls also post php -v & mysql -V results

mysql logs may be helpfull too.
if your databse gone away, there is main reason - your server resoures, and second - my.cnf settings
