[Zeek] File data loss in stream event

[王辰成]

Hi,
I'm sorry to bother you.
During using Zeek  I met some problem.  Could you help me?
I found a bro package named  credit-card-exposure(link
<https://packages.zeek.org/packages/view/75734569-4fb7-11e8-88be-0a645a3f3086>),
and  imitated the bro script
<https://github.com/sethhall/credit-card-exposure/blob/master/scripts/main.bro>
in this package  for detect some sensitive info.
 Part of the code is as follows

I printed the fields named seen_bytes and total_bytes of all the files, and
found that  many data of files  have not  entered the handler of stream
event. I  can also find  in files.log， the seen_bytes was far less than
total_bytes.
what  can I do  to solve this problem?

Yours respectfully
