Impact

Restart of tmm and re-negotiation of IPsec tunnels. Traffic disrupted while tmm restarts.

Conditions

Deletion of an expired ike-sa.

Workaround

None

Fix Information

The internal list data structure has been reorganized to use fewer entities in less-complex relationships. This makes it less likely for a corrupted list to occur, so this issue is less likely to occur.
