Hello,
I am not sure if this is the correct place for this, I have googled
around to see if anyone else has encountered such an issue, but I did
not find anything.
I am having this issue where after a period of time of no use (on beta
[production] environment), maybe 12 hours or so, the unicorn process
sleeps. When I go and re-request the page, it returns blank.
I am using Apache proxy to Unicorn.
My unicorn.stderr.log states:
I, [2015-07-01T03:07:05.168511 #13258] INFO -- : master done reopening logs
I, [2015-07-01T03:07:05.232546 #16222] INFO -- : worker=2 done
reopening logs
I, [2015-07-01T03:07:05.239934 #13308] INFO -- : worker=0 done
reopening logs
I, [2015-07-01T03:07:05.307616 #13311] INFO -- : worker=1 done
reopening logs
When I request the page again, it loads fine. It is only during the
process of "reopening logs" when it returns a blank page.
My unicorn.rb file:
worker_processes 3
# Load app into the master before forking workers
# for super-fast worker spawn times
preload_app true
# Listen on
listen "127.0.0.1:8550", :backlog => 1024
# Restart any workers that haven't responded in 180 seconds
timeout 600
# PID for the Unicorn master
pid "/var/www/r/shared/pids/unicorn.pid"
# Unicorn Log paths
stderr_path "/var/www/r/shared/log/unicorn.stderr.log"
stdout_path "/var/www/r/shared/log/unicorn.stdout.log"
before_fork do |server, worker|
##
# When sent a USR2, Unicorn will suffix its pidfile with .oldbin and
# immediately start loading up a new version of itself (loaded with a new
# version of our app). When this new Unicorn is completely loaded
# it will begin spawning workers. The first worker spawned will check to
# see if an .oldbin pidfile exists. If so, this means we've just
booted up
# a new Unicorn and need to tell the old one that it can now die. To
do so
# we send it a QUIT.
#
# Using this method we get 0 downtime deploys.
defined?(ActiveRecord::Base) and
ActiveRecord::Base.connection.disconnect!
defined?(OathKeeper) and OathKeeper.disconnect!
old_pid = '/var/www/r/shared/pids/unicorn.pid.oldbin'
if File.exists?(old_pid) && server.pid != old_pid
begin
Process.kill("QUIT", File.read(old_pid).to_i)
rescue Errno::ENOENT, Errno::ESRCH
# someone else did our job for us
end
end
end
after_fork do |server, worker|
##
# # Unicorn master loads the app then forks off workers - because of
the way
# # Unix forking works, we need to make sure we aren't using any
of the parent's
# # sockets, e.g. db connection
#
defined?(ActiveRecord::Base) and ActiveRecord::Base.establish_connection
defined?(OathKeeper) and OathKeeper.reconnect
end
Any help would be appreciated!
Thank you!
