Try catching the exception inside the main loop, to prevent your
program to exit in case of failure:

if __name__=='__main__':
  while True:
      err, det, tb = sys.exc_info()
      print "ERROR =>", err, det # gives you a description of the
occurred failure
      traceback.print_tb(tb) # this might be needed only for debug
