Symptom

Prime Infrastructure may fail to collect telemetry data from a managed Catalyst 9800 wireless LAN controller. On closer inspection, the "tdlcold" process in the Coral service became stuck in the CNDP_STATE_CON_INIT state. When the Coral container was restarted, the eWLC controller was able to reconnect and the Coral service's state was able to transition to CNDP_STATE_CON_CONNECTED.

Conditions

This was observed in Prime Infrastructure 3.8, managing a Catalyst 9800 wireless LAN controller.

Workaround

At this time, there is no workaround.
