Bug#582745: Workaround
I should also have mentioned - my workaround at the moment was to just rename the job.. I can't use the old job name until we reboot I guess :)
Bug#582745: Me too...
Throwing up my hand as well! Upstart, with a particular job, is in limbo (hung start/stop) until I reboot the relevant hosts, which at this time is not an option to maintain our 99.99%! This seems like a pretty serious bug .. surprised it's been here for 2 years and more people aren't screaming
