"There are stopped jobs." when exiting bash
If you have jobs that are stopped (with CTRL-z) or happened to be in the background but are stopped waiting for input, you can see what's there with the 'jobs' command. 

If you only have a job, then a 'fg' will bring it to the front for you to interact with it or kill with a 'CTRL-c'. If you have multiple jobs, you can bring individual or specific ones with 'fg '.
