Hello folks:

I replied in [1]. I think we could have a potential problem when executing
a DB change the impies a OF controller re-initialization. Most of the time
we don't have problems but as we see in the CI, we could sometimes.

I'll push a patch to add a retry decorator on the methods that trigger this
OF controller restart.

Regards.
