## 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.

  <br />

* The "`fw ctl zdebug + drop`" command shows this drop:

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

  <br />

* 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);`

  <br />

## 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.

<br />
