Bug #6499

Updated by Victor Julien about 1 year ago

I use trex v2.97 to test suricata v7.0.2 and found some problems. 

 1. The tcp.active_sessions and flow.active count in stats.log will never reduce to zero after trex stop. 

 The trex command: 

 <pre><code class="shell"> ```sh 
 ./t-rex-64 -f cap2/many_client_example.yaml -d 300 -p -m 30000 
 </code></pre> ``` 

 2. Sometimes the tcp.active_sessions will be a very big number at startup, looks like the int has overflow.
