Has anyone seen the following message and what does it mean:

15:33:59 [61922] <8> filter_image: unknown file type Q encountered,
continuing to process file  (size 0)
15:33:59 [61922] <2> getsockconnected: host=MASTER service=bpdbm
protocol=tcp port=13721
15:33:59 [61922] <32> validate_file_name: expected file /db/file.ds.011116,
found file 
15:34:00 [61922] <16> write_pl_messages: /db/file.ds.011116 was not
restored.

All the remaining files on the tape were also not restored.
I tried to restore this file(s) individually and it worked fine.
