Why are unicorn creating multiple master processes on startup in production mode? -

okay im trying setup production serven unicorn.

when try start unicorn server thru script have written starts 2 master instance.

this happens when start "-e production" given.

the init scipt start unicorn with:

#!/bin/sh set -e  timeout=${timeout-60} app_root=/application/path/current pid=$app_root/tmp/pids/unicorn.pid cmd="/usr/local/rvm/scripts/rvm && cd $app_root && bundle exec unicorn -d -e production -c $app_root/config/production/unicorn.rb" action="$1" set -u  old_pid="$pid.oldbin"  cd $app_root || exit 1  sig () {         test -s "$pid" && kill -$1 `cat $pid` }  oldsig () {         test -s $old_pid && kill -$1 `cat $old_pid` }  case $action in start)         sig 0 && echo >&2 "already running" && exit 0         su -s /bin/bash -c "$cmd" - www-data         ;; stop)         sig quit && exit 0         echo >&2 "not running"         ;; force-stop)         sig term && exit 0         echo >&2 "not running"         ;; restart|reload)         sig hup && echo reloaded ok && exit 0         echo >&2 "couldn't reload, starting '$cmd' instead"         su -s /bin/bash -c "$cmd" - www-data         ;; upgrade)         if sig usr2 && sleep 2 && sig 0 && oldsig quit                         n=$timeout                 while test -s $old_pid && test $n -ge 0                                         printf '.' && sleep 1 && n=$(( $n - 1 ))                 done                 echo                  if test $n -lt 0 && test -s $old_pid                                         echo >&2 "$old_pid still exists after $timeout seconds"                         exit 1                 fi                 exit 0         fi         echo >&2 "couldn't upgrade, starting '$cmd' instead"         su -s /bin/bash -c "$cmd" - www-data         ;; reopen-logs)         sig usr1         ;; *)         echo >&2 "usage: $0 <start|stop|restart|upgrade|force-stop|reopen-logs>"         exit 1         ;; esac 

uncorn config:

working_directory "/application/path/current" pid "/application/path/current/tmp/pids/unicorn.pid" stderr_path "/application/path/current/log/unicorn.log" stdout_path "/application/path/current/log/unicorn.log"  listen "/application/path/current/tmp/unicorn.application_name.sock" worker_processes 1 timeout 30  before_fork |server, worker|   defined?(activerecord::base) ,     activerecord::base.connection.disconnect!    old_pid = "#{server.config[: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     end   end end 

would realy appreciate help!

edit: hum... appears tough if write command "ps aux | grep unicorn" states 2 processes (1 master , 1 worker) why dos htop state have 5 processes active (2 masters , 3 workers)?

htop lists each thread of process separately, while ps doesn't. please read this answer more details.
