As we can see, there seems to be some bug that causes new

 127.0.0.1:7777, Signalling Weight: 1, Data Weight: 1

to show up for every test case execution.

I guess during the SNS-CONFIG procedure we somehow unconditionally create new objects rather than either
  1. first delete all objects, then create new ones, or
  2. check if the identical object already exists, and only create one if it doesn't
