No Space Left on Device and MySQL crashes

I’ve had periodic problems with MySQL crashes. It happens periodically and I can’t figure out why. I’ll restart the service and it works fine for a few days.

Now there’s a more immediate problem

I was copying the logs and I started getting errors that said “No space left on device.”

Same error happens when I attempt to create a directory using FTP “No Space Left On Device.” So I tried to re-log in FTP and I get this bit of luck: Status: Connection established, waiting for welcome message… Response: 220 ProFTPD 1.3.4a Server (Zpanel FTP Server) [::ffff:162.243.211.145] Command: AUTH TLS Response: 500 AUTH not understood Command: AUTH SSL Response: 500 AUTH not understood Status: Insecure server, it does not support FTP over TLS. Command: USER thelemur Response: 331 Password required for xxxxxxxx Command: PASS ********** Error: Could not connect to server

I restarted the droplet. I can use SSH to connect, but I still get the same No Space errors and ftp problems.

And now my sites look like SQL has crashed again. When I try to restart the service, I get “Job failed to start.”

If it matters, my droplet is Ubuntu 12.04, i’m using Apache and zpanel.

Anyone know what’s going on?
