Replace your
alert("Error in workerPool: "+errorObject.message+"  on
line"+errorObject.lineNumber);
with
 wp.sendMessage("Error in workerPool: "+errorObject.message+"  on
line"+errorObject.lineNumber,message.sender);

The next I don't understand, but we can try
commenting out
//  var serverresponse= message.body;
and
try change
       eval("dataarr="+serverresponse);
to
       eval("dataarr="+message.body);


Another thing:
The
  if (1)
  {
construct can be removed...
