If DB2 answered the buffer pool query of a database with an error message instead of the hit ratio table, e.g. SQL20249N The statement was not processed because the package named ... needs to be explicitly rebound., the service discovery created a bogus DB2 BP-Hitratios service from the words of that message, and the check crashed with KeyError or ValueError.

No services are discovered from such an error message any more. Existing DB2 BP-Hitratios services of the affected database now go UNKNOWN and show the DB2 error message.
