ACL6/4/RPC_FAILED:Failed to call synchronization IPC! (ErrorCode= [ULONG])


Failed to call synchronization IPC.


Parameter Name Parameter Meaning
ErrorCode Indicates the error codes, including the following:

2: indicates that memory allocation for sending messages failed.

3: indicates that synchronizing IPC timed out.

4: indicates that message waiting queue overflowed.

Possible Causes

When the ACL6 module sends information to the LPU, the RPC failed to call functions.


  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, RPC communication fails, which is normal. This log is informational only, and no action is required.
  3. Collect log information about RPC message sending failures of the LPU, and contact technical support personnel. For details, see Troubleshooting-Information Collection-Collecting Diagnostic Information.
