# Traffic stops working after a Security Gateway Member recovers from a failure

**Solution ID:** sk180705  
**Technical Level:** Basic  
**Product:** Scalable Chassis  
**Version:** R80.40 (EOS), R81 (EOS), R81.10 (EOS)  
**Last Modified:** 2023-08-14

## Symptoms

- Traffic stops working when a Security Gateway Member (SGM) recovers from a failure.

**Notes:**
  - The traffic keeps working after the SGM fails.
  - User Space Firewall is configured.

- The ```fw ctl zdebug + drop``` command shows this drop:

```
  dropped by fwmultik_process_f2p_cookie_inner Reason: connection not found (F2P);
  ```

- Example scenario:

1. SGM 1_02 handles the traffic.
  2. FWK crashes on SGM 1_02, and the traffic is distributed to SGM 1_03.
  3. SGM 1_03 handles the distributed traffic successfully.
  4. SGM 1_02 recovers from the failure and goes back to an ACTIVE state.
  5. The traffic is distributed back to SGM 1_02 and then stops flowing.
  6. Running 'fw ctl zdebug + drop' on SGM 1_02 shows this drop:

> ```
     dropped by fwmultik_process_f2p_cookie_inner Reason: connection not found (F2P);
     ```

## Cause

The connection was not removed from the SecureXL connection table when the User Space Firewall experienced a failure, such as when FWK process stops working.
