In files.log, the value of total_bytes is just taken from the HTTP Content-Length header.  Since the value of seen_bytes is less than total_bytes, you can suspect Bro didn’t see the full file for some reason.  Do you have a weird.log containing any obvious clues?  Else, I may need the original pcap to understand what went wrong.
