I have made a controller using Ryu which handles the paths and switches. The code seems to be working but I receive the following error. It is asynchronous meaning it does't seem to be related to any event and happens every once in a while. The thing is that those files are the Ryu files and I have not changed them.
I am using mininet to virtualize the network.
hub: uncaught exception: Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/ryu/lib/hub.py", line 52, in _launch

del self._map[link.src]
KeyError: <ryu.topology.switches.Port object at 0x7f92d4c5df10>
Any ideas?
Edit: Files:
