Hi shyamsundarn,

Can you give us a bit more information here? Specifically:

1. Size of the droplet
2. The output of your mysql logs and/or output of dmesg & /var/log/messages

From here, we can hopefully help narrow down the issue. It could be that mysql is crashing/being killed off by OOMkiller, but without that information, it’ll be difficult to answer why this is happening.

As a sidenote, rather than going through the trouble of restarting the droplet, you may want to see if mysql is running:

service mysql status

And/or

netstat -ntlp | grep :3306

If it’s not, you should just be able to start it back up using

service mysql start
