Script to help setup server on Linux

[cerbere]

this script helped me a lot to get things done.
now using the start script generated here I got a little issue, but I'm not sure it's effectivly an issue.
when i type ./start in my terminal i got this (I didn't paste the beginning) :

+ touch .lock-world
+ '[' 1 ']'
+ sleep 15
+ ./persist_world
+ '[' '!' -e .lock-launcher ']'
+ touch .lock-launcher
+ '[' 1 ']'
+ ./eqlaunch zone
+ '[' 1 ']'
+ ./chatserver
lotso@benlaptop:~/eqemulator/server$ + ./mailserver

so it's weird in the sense it doesn't go back to my prompt and it's stuck after ./mailserver and at the same time it goes to my prompt after ./chatserver is issued.
is there a typo somewhere or I'm doing something wrong ?
here is the part of my start script that corresponds to the output above, I dont see anything that would cause it to go back to my prompt after ./chatserver :

  # wait for shared memory to load
  sleep 15
fi

# Start up the official launcher.
if [ ! -e .lock-launcher ]; then
  # Create our lock file.
  touch .lock-launcher

  # Launch!
  ./eqlaunch $LNAME 2>&1 > logs/launcher &
fi

# Determine if we should start the chat server.
if [ $USE_CHAT_SERVER ]; then
  ./chatserver 2>&1 > logs/chatserver &
fi

# Determine if we should start the mail server.
if [ $USE_MAIL_SERVER ]; then
  ./mailserver 2>&1 > logs/mailserver &
fi
