Batch update returned unexpected row count from update [0]

[Stephen Michaels]

When I try to run the Cleanup or Checker Function, I'm getting this error:

Batch update returned unexpected row count from update [0]; actual row count: 2; expected: 1

It looks like the most_recent_checksum table does have several duplicate bitstream_id entries. What's the best way to fix this issue? Can I just delete those entries from the table directly?
