NS_E_CUB_FAIL_LINK
A productive reading of failed Content Server peer link begins at the component boundary where the named Content Server could not maintain its link to another server in the content topology.
Place in the component lifecycle
For failed Content Server peer link, legacy content-server links carry topology and content coordination between server identities. In the context of failed Content Server peer link, reachability, authentication, UID consistency, and post-outage reconciliation are separate checks; a TCP connection alone does not prove a healthy peer relationship. Use that architecture to locate the first component that changed state in failed Content Server peer link and to avoid treating a later summary message as the cause.
Important boundary for failed Content Server peer link. A peer-link failure is narrower than complete Content Server failure; each server may remain running independently. Keep the exact constant and returning API in the incident record for failed Content Server peer link, because legacy components sometimes use similar wording for different object layers.
Build a reliable incident timeline
| Preserve | Why it matters |
|---|---|
| Both server identities/UIDs, endpoint addresses, transport, and failure timestamp | Separates configuration or identity from storage, parser, network, or lifecycle state for failed Content Server peer link. |
| Name resolution, authentication, network path, heartbeat, and packet-loss data | Provides a stable before/after comparison for the proposed correction for failed Content Server peer link. |
| Peer configuration and expected topology on both sides | Shows whether the status is expected information, a warning, or the first failure in the event sequence for failed Content Server peer link. |
| Content or restripe/rebuild operations dependent on the link | Ties the message to one server object and one transition instead of a later retry for failed Content Server peer link. |
For failed Content Server peer link, prefer identifiers, versions, counts, hashes, state transitions, and redacted paths; media content, credentials, keys, and user data are rarely needed in routine incident logs.
Tests that change one variable
- Test the endpoint path and credentials in both directions. Retain a known-good stream, session, or server object so a broad restart is not mistaken for repair of failed Content Server peer link.
- Compare one healthy peer link using the same network route. For failed Content Server peer link, record the first server event, object state, or return value that changes.
- Interrupt and restore a test link to validate fail/unfail detection. Keep media bytes, server identity, and unrelated publishing-point settings fixed while testing failed Content Server peer link.
Do not use repeated reconnects as the main test for failed Content Server peer link; a later success can belong to a new session, publishing-point generation, server owner, completed background operation, or different media path.
Interpretation boundaries
| Observed comparison | Interpretation for failed Content Server peer link |
|---|---|
| A known-good object succeeds through the same component | For failed Content Server peer link, the platform path exists; concentrate on the production object, identity, metadata, or state captured above. |
| The control fails at the same first operation | For failed Content Server peer link, preserve server, storage, plug-in, topology, and network evidence before modifying media or publishing-point data. |
| The status changes after one deliberate adjustment | For failed Content Server peer link, the diagnostic boundary moved; the replacement status now describes the next contract to investigate. |
Repair and regression proof
Correction for failed Content Server peer link: Repair networking, identity, endpoint, or peer configuration and reconcile state missed while the link was down. Keep the original server configuration, event sequence, object inventory, input hash, and topology snapshot for failed Content Server peer link so the change can be reversed and explained.
Accept the repair only when the link remains established under content traffic, both peers agree on UID/topology, and the matching recovery event occurs once. Repeat the original supported operation under the original identity and object state; a simplified media file, replacement server, new session, or different client is useful comparison evidence but not final regression proof for failed Content Server peer link.
