PEERDIST_ERROR_INVALIDATED
The supplied object has already been invalidated.
PEERDIST_ERROR_INVALIDATED is Win32 error 4057 (0xFD9) and belongs to Peer Distribution and BranchCache object lifetime after cancellation or teardown. 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 object lifetime after cancellation or teardown rather than starting with a broad system repair.
Where the result appears
- This result can surface during the object lifetime after cancellation or teardown stage of a PeerDist publisher or consumer.
- This result can surface during a BranchCache request where the supplied PeerDist object has been invalidated and cannot accept further operations.
- It can surface during an API call whose diagnosis depends on record the invalidating operation, object handle, generation, and later caller.
- It can surface during a recovery path that must release the stale object and reopen or recreate state from authoritative content information.
Likely causes
- the supplied PeerDist object has been invalidated and cannot accept further operations.
- the caller made a stale assumption during object lifetime after cancellation or teardown.
- the observed PeerDist state no longer matched record the invalidating operation, object handle, generation, and later caller.
- the wrapper retried before it could release the stale object and reopen or recreate state from authoritative content information.
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 object lifetime after cancellation or teardown because a blind retry can hide stale state or repeat a non-idempotent change.
- record record the invalidating operation, object handle, generation, and later caller.
- record the exact PeerDist function involved in object lifetime after cancellation or teardown.
- record the object generation used for object lifetime after cancellation or teardown.
- record PeerDistSvc status while evaluating the supplied PeerDist object has been invalidated and cannot accept further operations.
- record origin fallback behavior before attempting to release the stale object and reopen or recreate state from authoritative content information.
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 4057, hexadecimal 0xFD9, 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 the supplied PeerDist object has been invalidated and cannot accept further operations. Prove or disprove that proposition using record the invalidating operation, object handle, generation, and later caller together with the exact PeerDist function involved in object lifetime after cancellation or teardown. 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 cancel path invalidates a retrieval object, but a timer later uses the old handle. Generation checks prevent the stale access. The negative case should keep the responsible condition unchanged and confirm error 4057; the recovery case should change only that condition and verify a successful result without an unrecorded side effect.
Suggested diagnostic fields
For error 4057, keep winerr_4057_api, winerr_4057_object, winerr_4057_state_before, winerr_4057_request, winerr_4057_first_status, winerr_4057_verification. These fields distinguish the initial state, requested transition, first status, and verified recovery result.
Handling, retry, and recovery
release the stale object and reopen or recreate state from authoritative content information 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 object lifetime after cancellation or teardown. 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 4057, hexadecimal
0xFD9, and the producing API. - log the target object and observed Peer Distribution and BranchCache object lifetime after cancellation or teardown 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
ALREADY_COMPLETED can apply to a completed operation; INVALIDATED says the object itself is no longer usable.
Practical example
A cancel path invalidates a retrieval object, but a timer later uses the old handle. Generation checks prevent the stale access.
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 4057, changes the responsible condition, and confirms that the same operation succeeds without hidden data loss.
