ERROR_RECEIVE_EXPEDITED
What ERROR_RECEIVE_EXPEDITED means
A network transport delivered data marked as expedited or out-of-band. In practical terms, this status belongs to transport priority data: the remote peer sent data through the protocol mechanism for urgent or expedited delivery.
Typical causes
- A protocol uses TCP urgent data or an equivalent transport feature
- A legacy TDI client distinguishes normal and expedited receive paths
- The remote endpoint signaled high-priority control information
How to investigate
- Capture transport flags and peer endpoint
- Verify that the application has a defined expedited-data handler
- Check whether middleboxes or protocol conversions preserve the expected semantics
Developer guidance
Do not append expedited bytes blindly to the normal application stream. Their meaning is protocol-specific and often represents control rather than payload.
Operational interpretation
When ERROR_RECEIVE_EXPEDITED appears, first determine whether the operation actually failed, completed with an informational condition, or transferred work to another component. Record the API name, returned value, affected process or object, and the immediately preceding event. For this code, the most useful boundary is the transport priority data boundary; broad machine-wide remediation before that boundary is identified can hide the original evidence.
Example scenario
An incident begins when a protocol uses TCP urgent data or an equivalent transport feature. A responder investigating this result should not begin with a generic reboot that destroys the original context. A better first step is to capture transport flags and peer endpoint. That evidence connects it to its producing operation and reveals whether this particular result is repeatable, expected, or merely secondary.
Logging and telemetry
Telemetry for this Win32 error should preserve its numeric value, component version, process and thread identifiers, operation name, affected object or endpoint, elapsed time, and the first earlier failure in the same activity. Keep the result correlation identifier stable across callbacks so the status can be joined to the request that initiated this exact operation.
Recovery and validation
Apply recovery only after the responsible state has demonstrably changed. After changing that state, repeat one controlled this result scenario and verify both the returned status and the resulting system state. Absence of another log line is not sufficient: confirm that the intended transport priority data action completed, that no resource remains pending, and that later cleanup does not produce a different secondary error.
