Help

hello ,
i’ve wrong configuration with --af-packet mode cause this :

af-packet:
  - interface: ens33
    threads: 12
    defrag: yes 
    cluster-type: cluster_flow
    cluster-id: 98
    copy-mode: ips
    copy-iface: ens37
    buffer-size: 64535
    use-mmap: yes
  - interface: ens37
    threads: 12
    cluster-id: 97  
    defrag: yes
    cluster-type: cluster_flow
    copy-mode: ips
    copy-iface: ens33
    buffer-size: 64535 
    use-mmap: yes

but why ?Putting the configuration on top will keep my connection to the websites in supend mode, but if I switch to NFC mode, I won’t have any problems.

i’v this too:

run-as:
  user: suricata
  group: suricata

```, and this 

regards
