Thank you very much, everything works fine now! Just removed all dbfarm subdirectories and the error message disappeared. And no, there were no important XML documents stored in the database, only some XMark generated streams ;-)!

Nevertheless: I never shredded any document before encountering the problem the first time. Before I /only/ used direct loading from the query. I just tried shredding to solve the problem...

Hope this helps to locate the bug!
