Check MySQL to see if all of the data loaded.

The ssh connection was killed, so you don't know how the shell did.

If you need to run long commands on remote systems, use screen or tmux on
the remote system. That will keep the shell running even if the network
connection is killed. It also allows you to reconnect to the shell.

screen -S mysession # Start a screen session named mysession
screen -x mysession # reconnect to the screen session named mysession

<ctrl>-a d # disconnect from an active screen session

If you already run screen locally you can either run screen within screen
or you can start a new xterm, then connect out.

I also recommend the ServerAliveInterval, but I set it to 5 minutes. I
used that for all ssh connections.

ServerAliveInterval 300

ciao,
