This indicates that two processes are trying to use the same port at the same time. Usually, this means that you have two copies of something running, by accident. But, it can also mean that you've got a configuration entry that creates a server endpoint, on a fixed port, and you are not using a "static" instance, but instead, a dynamic instance that is created multiple times.
Look to make sure you aren't creating two of something.
