Subject: unicorn worker partially restarted when using USR2
Date: Sat, 7 May 2011 19:54:11 +0800 [thread overview]
Message-ID: <BANLkTi=Fh0iSkUhWP_Hss-LRRe0_sGHUbA@mail.gmail.com> (raw)
In the deployment I did kill -s USR2 `cat unicorn_pid` to gracefully
restart unicorn. But I noticed that unicorn workers were partially
restarted when using USR2.
The following is how I did test:
start unicorn in production environment:
the action has the following code:
def index
logger.info "-----------------------------------------fooo bar ---------"
logger.info "-----------------------------------fooo bar ---------"
end
then changed the code to:
def index
logger.info "--####---------------------------------fooo bar ---------"
logger.info "-----------------------------------fooo bar ---------"
end
and run kill -s USR2 `cat unicorn_pid`
and then tail the production.log (after several minutes)

So it seems that unicorn was just partially restarted.
