I am seeing an unexpected behavior where my 'screens' are closing and my Runit services ('rails server') are not running when I log off my Ubuntu 12.04 box. I'm logged in as 'ubuntu' and essentially all background processes own by 'ubuntu' is pausing when the SSH session ends. However, they all resume after I SSH back into the server.
To debug this, I'd like to see what the system is doing after I log off the box. Any suggestions which logs I should I look at or which services should enhance the log level of to see what's going on?
Thanks in advance, -Khiem
