Hi oisf-users team,
I am testing the file extraction function of Suricata version 5.0.2.
pcap was used in the ".lst" file format.
Also used the "--pcap-file-continuous" option.
I have 2 questions.
If the same rule and the same packet are tested many times, the timestamp of the detected packet will be detected differently.
Information other than the time stamp and flow_id match.
I want to know why the timestamp value was detected differently each time.

When extracting files from ftp pcap, detection may not be possible.
Detects about once in a maximum of 10 inspection operations.
For testing, i used the same rules and the same pcap. (Pcap size is 94k and small size.)
If detected and not, I want to know why it is displayed in the same pcap.

Attached files such as pcap, rule, and .yaml used in the test to the email. 
Ftp also includes a fast.log file.
Can you help me with any related issues?
Thank you for your time.
We look forward to your reply.
JK Lee
