Several Kytos Errors Found when Creating and Deleting Multiple EVCs

[dgarc330]

We were running code to test the controller's ability to create and delete multiple EVCs one after another. The code we were using is the same as the one Antonio developed for testing the mef_eline and can be found here: https://github.com/ajoaoff/mef_eline/blob/tests/tests/integration/tests/test1.sh

The errors starting popping up after we had created and deleted a couple hundred EVCs, and then started showing up more recently after the creation of just a few EVCs.

I have put in bold the beginning of each error messages so they can be easily seen where each one starts and ends.

[ajoaoff]

I'm closing this issue here and reopening it in the storehouse repo, as the problem seems to be there.
