## Symptoms

- * "Encryption failure: Unknown SPI: 0xXXXXXXXX for UDP encapsulated IPsec packet" log appears repeatedly in SmartView Tracker after Phase 2 re-key of a Remote Access client.
* After another negotiation by the same client, issue is resolved for some time.
* Client shows as it is still connected, but there is no access to internal resources of the encryption domain.

## Cause

When a remote user disconnects or reconnects, and IKE SA has been revoked (expired or deleted), but IPSEC SA hasn't, there is a leak in the outbound IPSEC SA.
