Impact

APM end users will not be able to log in.

Conditions

1. APMD detects TMM restart 2. APMD then recreates configuration snapshots when TMM becomes ready. 3. TMM restarts and becomes ready again. 4. APMD checks TMM status again but concludes that TMM is still down.

Workaround

Restart APMD to recover when there is configuration snapshot.

Fix Information
