PEERDIST_ERROR_OUT_OF_BOUNDS

An operation accessed data beyond the bounds of valid data.

PEERDIST_ERROR_OUT_OF_BOUNDS is Win32 error 4061 (0xFDD) and belongs to Peer Distribution and BranchCache content range validation. The system description identifies the immediate condition but does not identify the caller, object, policy, device, service instance, or transition that produced it.

Interpret this result at the API boundary that returned it. Capture it before logging, cleanup, or another Windows call can replace the thread-local last-error value. Compare the recorded inputs with the documented precondition for Peer Distribution and BranchCache content range validation rather than starting with a broad system repair.

Where the result appears

  • This result can surface during the content range validation stage of a PeerDist publisher or consumer.
  • This result can surface during a BranchCache request where an offset or length addresses bytes outside the valid content extent.
  • It can surface during an API call whose diagnosis depends on record total content length, overlapped offset, requested length, and arithmetic before the API call.
  • It can surface during a recovery path that must validate range addition for overflow and clamp only when the protocol explicitly permits partial data.

Likely causes

  • an offset or length addresses bytes outside the valid content extent.
  • the caller made a stale assumption during content range validation.
  • the observed PeerDist state no longer matched record total content length, overlapped offset, requested length, and arithmetic before the API call.
  • the wrapper retried before it could validate range addition for overflow and clamp only when the protocol explicitly permits partial data.

Diagnostic sequence

Diagnosis of it starts with the exact request type: read, write, create, transition, validation, cancellation, or administrative action. Identify the object generation and subsystem owner, then decide whether the failure happened before side effects, during a partial transition, or after completion. This ordering matters in Peer Distribution and BranchCache content range validation because a blind retry can hide stale state or repeat a non-idempotent change.

  • record record total content length, overlapped offset, requested length, and arithmetic before the API call.
  • record the exact PeerDist function involved in content range validation.
  • record the object generation used for content range validation.
  • record PeerDistSvc status while evaluating an offset or length addresses bytes outside the valid content extent.
  • record origin fallback behavior before attempting to validate range addition for overflow and clamp only when the protocol explicitly permits partial data.

Correlate it with the owning component’s operational log, the Windows System log, and any subsystem trace. Telemetry for this Win32 error should preserve native identifiers such as a path or file ID, handle generation, node or peer identity, policy ID, object version, offset and length, or transaction token. Retain decimal 4061, hexadecimal 0xFDD, and the producing API even when a localized message is also shown.

State boundary to prove

The decisive boundary for this Win32 error is whether an offset or length addresses bytes outside the valid content extent. Prove or disprove that proposition using record total content length, overlapped offset, requested length, and arithmetic before the API call together with the exact PeerDist function involved in content range validation. When observations for this Win32 error disagree, preserve both and inspect the transition between them instead of choosing the more convenient value.

A focused validation for this Win32 error should recreate the relevant part of this situation: a 32-bit length calculation wraps before PeerDistClientAddData and produces an offset beyond end-of-content; checked arithmetic fixes it. The negative case should keep the responsible condition unchanged and confirm error 4061; the recovery case should change only that condition and verify a successful result without an unrecorded side effect.

Suggested diagnostic fields

For error 4061, keep winerr_4061_api, winerr_4061_object, winerr_4061_state_before, winerr_4061_request, winerr_4061_first_status, winerr_4061_verification. These fields distinguish the initial state, requested transition, first status, and verified recovery result.

Handling, retry, and recovery

validate range addition for overflow and clamp only when the protocol explicitly permits partial data A retry is justified only after the recorded state that produced this specific code has changed.

Retry it only after evidence shows a change in Peer Distribution and BranchCache content range validation. Initialization, asynchronous completion, recall, or service readiness can justify bounded backoff; malformed metadata, invalid identifiers, policy rejection, unsupported versions, and integrity failures require correction. Before repeating a write or configuration operation after it, query completion state explicitly.

What to log for support and telemetry

  • log decimal 4061, hexadecimal 0xFDD, and the producing API.
  • log the target object and observed Peer Distribution and BranchCache content range validation state.
  • log caller identity, process and thread IDs, machine or node identity, and UTC time.
  • log attempt number, elapsed time, previous result, and any partial side effect.
  • retain the first lower-level or component-specific error before Win32 translation.

Difference from nearby codes

MISSING_DATA concerns a valid range that cannot be found; OUT_OF_BOUNDS says the range itself is invalid.

Practical example

A 32-bit length calculation wraps before PeerDistClientAddData and produces an offset beyond end-of-content; checked arithmetic fixes it.

Developer and administrator guidance

Code that handles it should keep its Win32 domain visible across exceptions, RPC responses, and JSON or REST wrappers. Administrators should verify the subsystem evidence before changing policy, deleting state, forcing failover, or replacing storage. Recovery is demonstrated only when a test observes 4061, changes the responsible condition, and confirms that the same operation succeeds without hidden data loss.
