Error compiling trigger DBA.RDB2RDF_AD__`CSV`~`DBA`~`X` on CSV.DBA.X

Hi,
I have this errors, starting Virtuoso istance:

INFO: ERRS_0 37000 SP031 SPARQL compiler: QUAD MAP 'sys:qm-c49af9060b4acfc88454224157b21013' group pattern refers to undefined quad map
ERROR: Error compiling trigger DBA.RDB2RDF_AD__`CSV`~`DBA`~`X` on CSV.DBA.X: 37000: SQ074: Line 12: SP031: SPARQL compiler: QUAD MAP 'sys:qm-c49af9060b4acfc88454224157b21013' group pattern refers to undefined quad map -- create trigger "RDB2RDF_AD__`CSV`~`D`DBA`~`X'

Any ideas to solve this ERROR, QUAD MAP: ‘sys:qm-c49af9060b4acfc88454224157b21013’ is missing…

Did you have some CSV attachments that were mapped to RDFViews at some point ? As it looks as if the RDF Quad Maps have been partially removed with parts of the mapping still remaining.

Thus would need to know more about wha CSV or other attachments were being mapped to RDF and what else is in the Virtuoso log on startup ?

Generally there messages can be ignored as they wouldn’t affect the database behaviour …
