RPC_X_PIPE_DISCIPLINE_ERROR - 1917 (0x77D)

The RPC call completed before all pipes were processed.

Updated: Feb 21, 2026

Introduction

This article provides a detailed explanation of the RPC_X_PIPE_DISCIPLINE_ERROR error code, which is specific to Remote Procedure Call (RPC) operations in Windows. The error indicates that an RPC call completed prematurely due to issues with pipe processing.

Technical Meaning

The RPC_X_PIPE_DISCIPLINE_ERROR error signifies that during the execution of an RPC call, the system detected a problem related to how pipes were managed or processed. Specifically, it suggests that the call terminated before all expected pipes could be fully processed, leading to potential data loss or incomplete processing.

Error Details

The error code 1917 (0x77D) is returned when an RPC operation encounters a situation where the pipe discipline does not align with the expected behavior. This can occur in various scenarios involving network communication and data transfer between processes or machines.

Usage Context

This error typically arises in environments where RPC calls are used for inter-process or inter-machine communication, particularly over networks. It is relevant to applications that rely on RPC services for data exchange, such as distributed computing frameworks, networked applications, and certain system utilities.

Developer Interpretation

Developers should interpret this error as an indication that the RPC call did not complete its intended operations due to issues with pipe management. This could be caused by various factors, including incorrect parameter values, corrupted data, or limitations in the system's ability to handle the operation correctly.

Related Errors

  • RPC_X_PIPE_LIMIT_EXCEEDED (1920): Indicates that a pipe limit was exceeded during an RPC call.
  • RPC_X_PIPE_NOT_FOUND (1918): Suggests that a required pipe could not be located or identified during the RPC operation.

FAQ

Q: What does the RPC_X_PIPE_DISCIPLINE_ERROR error mean?

A: It indicates that an RPC call completed prematurely due to issues with pipe processing, suggesting potential data loss or incomplete operations.

Q: How can I troubleshoot this issue?

A: Review the context of the RPC operation and validate parameters, ensure correct object types, verify input data integrity, and check system limits or constraints.

Summary

The RPC_X_PIPE_DISCIPLINE_ERROR error code (1917) is specific to issues encountered during RPC operations related to pipe processing. Developers should be aware of this error when working with networked applications that rely on RPC services for data exchange and take appropriate steps to ensure correct parameter usage, validate input data, and handle system limits appropriately.
