I have an odd issue, and I'm writing to see if anyone has seen the same issue. If I use "jexec 4 tcsh" or ssh into the jail, some sequences on the command line kick me out (spontaneously exit) everytime. For example, I run a couple of commands, then go to the /usr/local folder, hit mv TAB (file name completion) realize I am in the wrong folder, hit ^C, and the jail boots me. I've set the 'prompt' to be HOST and GUEST for the main install and jail.
