Sorry to be asking this again, I see it [has been asked before](https://stackoverflow.com/questions/17633881/how-can-i-solve-unable-to-find-consistent-port-localhost-app-engine-error?rq=1), but there were no answers, and I still have this problem. I did not know how to ping the question. :)

I have periodic problems running the Google App Engine development server on localhost.
I want to stress that they are periodic problems, that I have a hard time figuring out where stems from.
I am running on Mac OS X Mavericks.

I am mostly working from two locations, and it has previously been working both places, now I only have the problem in one location. I have tested stupid moves as being on wired or wireless, or even without internet.

I run

```
dev_appserver.py ShoppingList/

```

And get the following output

```

```

I have tried the solutions on the BindError from the other answers:
[Apps won't run on GAE - 'unable to bind to localhost:0'](https://stackoverflow.com/questions/15985130/apps-wont-run-on-gae-unable-to-bind-to-localhost0)

[Failed to start devlopment server -- BindError: Unable to find a consistent port localhost](https://stackoverflow.com/questions/16688582/failed-to-start-devlopment-server-binderror-unable-to-find-a-consistent-port)
I have no other instances of the server running, I have only one localhost in my /etc/hosts and it does not help to run on a different port. 

Notice that the Error is only thrown to 'localhost' not a 'localhost:0' or some specific port as in other questions. I do not know if that provide any info.

All help will be appreciated.
