Description

Suricata version: 2.0.9
OS: Ubuntu 15.04
pcap url: download by the http://pan.baidu.com/s/1mgrNMRI;
suricata.yaml: download by the attachment;
files rules: download by the attachment;

when I use suricata 2.0.9 to extract file from the traffic, the target file is truncated into several file.x and file.x.meta. So, I test suricata by using the pcap file, the result is the same. Please help me, thank you for your help.

eve.log: download by the http://pan.baidu.com/s/1c0mE4PM
when I check the eve.log, the http session of the pdf file is truncated into several sessions, for example:

That could explain why is it truncated.
Can you try to reproduce that with a much smaller pcap (than 1.5GB)?
