Is there any way
supervisord can automatically restart a failed/exited/terminated job and send me a notification email with a dump of the last x lines of log file?

You install it with "easy_install superlance" or download it at: http://pypi.python.org/pypi/superlance

Regarding the automatic restart: you should make sure that autorestart is set to true (it is set to unexpected by default). This way the package will be restarted 3 times. If after that it still exists it gives up but you can change that with startretries.
