An error occured while trying to export SAF of a collection

[Elaine Ding]

Dear all, 

I tried to export DSpace collection by  using following dspace 

/bin/dspace packager -d -a -t AIP -e admin@myu.edu -i 4321/4567 aip4567.zip

Exception: java.io.FileNotFoundException: /opt/local/dspace-data/assetstore/94/02/21/94022110151281798908617968664777106972 (No such file or directory)

There is not directory and folder for this bitstream, I saw it is marked as BITSTREAM_NOT_FOUND in checksum_history

any suggestion to remove this bitstream and solve this issue ?

Thanks

Elaine
