Discovery data generated by discovery source id '%1' has invalid topology relationships. This can be due to the following reasons:

-- More than one discovery data item describes relationships for the same health service id.
-- The discovery data contained entity instances; only relationships should be generated.
-- The relationships were not agent communication relationship types.
-- The source entity instance id specifies a singleton type.

No existing topology relationships were changed.
