Description (partial)

Prime Infrastructure 3.8 may become unable to see the AP or Client count from a Catalyst 9800 eWLC, because the telemetry BIPC between the 9800 and Prime Infrastructure's Coral service gets stuck.

eWLC#show telemetry internal protocol cntp-tcp c c q
Telemetry protocol connector queue counters:
Protocol      : cntp-tcp
Queue max len : 256000000
Packets count : 190470  --> Queue is stuck
High watermark: 255999769
At The same time, Coral shows:
:Ex-Renderer Stats: 
  Number of retries,1
  Number of disconnects,1
  IPC state,EXR_IPC_STATE_CONNECTING  --> Connecting state

This was observed in the normal operation of Prime Infrastructure and the eWLC.
