Comment 16 for bug 2015103

I'm tempted to bump the retry_on_exception to see if that fixes this, at least for testing purposes. It seems likely that it just needs more time to settle before the ports match. Currently we have:

@retry_on_exception(5, base_delay=3, exc_type=RetryProxyManagerCall)
def _proxy_manager_call(path, api_version, args, kwargs):

which retries at
3 seconds
6 seconds
9 seconds
12 seconds
15 seconds

before failing.
