</div>Actually, this is not how it works.<br>
<br>
If unrecoverable packet loss is encountered (data segments lost) a<br>
stream event is set:<br>
<br>
stream-event:reassembly_seq_gap;<br>
<br>
The stream-events.rules file contains this rule:<br>
<br>
alert tcp any any -> any any (msg:"SURICATA STREAM reassembly sequence<br>
GAP -- missing packet(s)"; stream-event:reassembly_seq_gap; sid:2210048;<br>
rev:1;)<br>
<br>
At this point the http parser lost track and gives up, and so will not<br>
emit errors.<br>
