Oracle 12.2 shows high parse per execution ratio for unknown lob$ query

In an AWR report I see the following (most liekly recursive) query which happens very often and is parsed each time: select obj#, intcol#, ts#, file#, block#, property from lob$ where lobj#=:1 The AWR entry for SQL ordered by parse calls: Parse Calls Executions % Total Parses SQL Id SQL Module SQL Text 411,384 411,414 39.62 6y55dxn24t86q select obj#, intcol#, ts#, fil... Any idea which component is generating that and why it is not a prepared statement? (since our app sets "module" everywhere we know its not directly executed from us). We do use LOBs heavily, so this can be related to reorganisation or maybe data guard?
