The failing call is in server/site_crashcollect.py, in
_resolve_crashserver().  Here's the relevant call:
    if not crashserver_name:
        metrics.Counter('chromeos/autotest/crashcollect/could_not_resolve'
                        ).increment()
        raise dev_server.DevServerException(
                'No crash server has the capacity to symbolicate the dump.')
    else:   
        metrics.Counter('chromeos/autotest/crashcollect/resolved',
                        fields={'crash_server': crashserver_name})
