Symptoms

If intra-chassis failover is triggered in a loaded chassis, the tmm crashes in some cases of subscriber creation.

Impact

TMM crashes. The slot reboots, potentially triggering further daglib hash changes. May result in cascading core under load. Traffic disrupted while tmm restarts.

Conditions

-- The chassis is loaded with many blades. -- The HA configuration is intra-chassis. -- RADIUS subscriber is added with custom attributes. -- The subscriber attributes are corrupted or erased.

Workaround

None.

Fix Information

If intra-chassis failover is triggered in a loaded chassis, the tmm no longer crashes in some cases of subscriber creation.
