Sometimes Minecraft will halt and won't respond to stop commands. When this happens you'll need to terminate the process.

Terminate the java process.

1. Log into your server using PuTTY. See our Using PuTTY on how to do that.
2. Type top into the command line.
3. Find the process that says java on the right side. Or the process that is using the largest amount of cpu power, ie: 100%, 200% etc.
   

   

4. Hit Ctrl+C to exit the processes screen.
5. Now back at the command line, type kill -9 PID# (see screenshot)

   

6. Type top again to confirm java's gone. If not, try step 3 again.
   

Now that Minecraft's stopped, you can start Minecraft as normal and/or close PuTTY.
