These warnings shouldn't be ignored. The defaults which are coded
in the RA are what the author of the RA advised as minimum. These
values are, however, not used automatically by the CRM, so they
need to be specified in the configuration. And then the resources
should be thoroughly tested to see if the timeouts are meaningful
in the given environment.
