# Traffic Recognition Issue on Single-Core Machine/Connection Timed Out

While single-core machines are not recommended for a production environment, they can be a resourceful way to test and demo with the open-apspec. If the agent is failing to recognize traffic on a single-core machine, and you observe a connection timed-out error in the NGINX error logs (`/var/log/nginx/error.log`), please follow the steps below to resolve the issue:

1. **Check NGINX Logs:**
   * Open the NGINX error logs using the following command:

     ```
     cat /var/log/nginx/error.log
     ```
   * Look for any connection timed-out errors. This will provide valuable information about the issue.
2. **Navigate to Configuration File:**
   * Locate the configuration file at `/dev/shm/cp_nano_http_attachment_conf`.
3. **Update Registration Thread Timeout:**
   * Open the configuration file and find the parameter `registration_thread_timeout_msec`.
   * Change the value from `100` to `200`.

     ```conf
     registration_thread_timeout_msec 200;
     ```
4. **Restart NGINX:**
   * After making the changes, restart NGINX to apply the configuration updates.

     ```bash
     sudo service nginx restart
     ```

These steps should help address the issue of traffic recognition on a single-core machine when using the open-appsec. However, it's strongly recommended to use hardware that meets the recommended system requirements for optimal WAF performance in a production environment.
