ruby - Stopping kill command -

i have ruby application.
application consist of scheduled jobs, take places @ every 2 or 3 hrs or more continuously.
regularly make changes application, therefore have kill application , re-run again.
follow these 3 steps

ps -ef|grep rackup kill -9 pid rake run 

so therefore scheduled jobs effected, if under execution...
way stop kill -9 command till jobs finished (may locks or script)

you need rescue systemexit exceptions, or use trap or at_exit signal handlers. more info here.
