The MPU failed to send IPC messages to an LPU.


Parameter Name Parameter Meaning
[ULONG] Indicates the slot ID of the LPU.
[STRING] Indicates the message name.

Possible Causes

The LPU was abnormal.


  1. Run the display device command to check whether the LPU has registered.

    • If so, go to step 3.
    • If not, go to step 2.

  2. If the LPU has not registered, IPC communication fails, which is normal. This log is informational only, and no action is required.
  3. Collect log information about IPC message sending failures of the LPU, and contact technical support personnel. You can collect diagnostic information using the display diagnostic-information command.
