SSH remote control question

I am pretty new to linux so forgive me for asking a basic question :P

I am using SSH to control 40 machines. What i am trying to do is remotely bash a shell script on each machine. I am using a for loop to bash every script, code as follows.

code in host machine runallworkers.sh:

Code:

...

i=1

for each $ip[] in ip[]   #just for example, i have saved all ips in a array ip[]
do
SSH -i aaa.rsa ubuntu@${ip[]} 'bash /home/ubuntu/program/runworker.sh'
echo "running worker in node $i"
let i++
done
...

code in each runworker.sh in each worker machine:

Code:

./worker.pl 7000 &
#worker.pl is a socket server program. it takes the parameter 7000 to run. it listens to port 7000

i can manually bash the runworker.sh file in each worker machine. So the worker.pl file should work fine. I can use the for loop to do other stuff on each node, so the loop should work fine too.
But the problem occurs when i run the script in the host machine, it stop responding after the first bashing, so the loop can not go on... the screen shows something like this:

Code:

ubuntu@1.1.1.1:~$ bash runallworkers.sh
running worker in node 1

please someone help me out...
Thanks in advance!!

NAME

       worker - file manager for the X Window System

SYNOPSIS

       worker [options]
       worker [directory1[ directory2]]

DESCRIPTION

       worker  is  a  graphical  file manager for the X Window System.	It uses the classical two-panel view of the files and directories.  It has
       many internal operations while any external program can also be used for operating on the selected items.
       You can easily add actions to filetypes or buttons with the builtin configuration program.
       For details read the documentation available at the Worker homepage (see below).

OPTIONS

       -h, --help
	      This shows a little help about options and quits immediately

       -V, --version
	      This shows the program version

       Any other argument will be interpreted as directory to show on the left side.
       A second argument can be a directory to show on the right side.

SIGNALS

       SIGUSR1 causes Worker to stop executing the command list, useful when stuck in an endless loop.

ENVIRONMENT

       WORKER_XEDITOR
	      overrides the editor used by Worker in the default configuration.

FILES

       ~/.worker

	      Worker's configuration directory.
