NS_E_MAX_BITRATE
NS_E_MAX_BITRATE — 0xC00D0047
What the limit means
NS_E_MAX_BITRATE means the requested operation would exceed a configured maximum bandwidth limit. This is a policy/ceiling result: first identify which server, publishing point, plug-in or request limit supplied the ceiling rather than treating it as evidence of packet loss.
Measurements that matter
- Configured maximum bandwidth and the configuration object that owns it.
- Bitrate requested by the new stream or operation and the bitrate already committed to active work.
- Publishing point/content identity and whether multiple bitrate variants are involved.
- Active sessions or stale reservations that contribute to the same limit.
Evidence to collect
| Field | What to preserve |
|---|---|
| Ceiling | Exact configured limit, its unit and the server/publishing-point object that owns it. |
| Current use | Measured count/rate/size immediately before the rejected request. |
| New demand | Amount the new operation would add to the same resource. |
| Owners | Sessions, titles, streams or reservations contributing to the measured usage. |
Decision rule
The result is proved only when recorded usage plus the new demand crosses the recorded ceiling; otherwise investigate stale accounting or the object that owns the limit.
Focused test
Keep the same content and reduce only the bandwidth demand below the recorded ceiling, or change only the documented ceiling. A successful retest demonstrates the limit relationship; changing transport, proxy and content at the same time does not.
Distinguish it from available bandwidth
NS_E_INSUFFICIENT_BANDWIDTH reports that available bandwidth cannot satisfy the request. NS_E_MAX_BITRATE instead identifies a maximum-bandwidth ceiling. Record both the demand and the configured limit so the two conditions do not collapse into the same “network is slow” diagnosis.
Verification
Repeat the original request and confirm measured demand stays within the configured ceiling. Also retain one boundary test that intentionally exceeds the limit and still returns the expected limit result.
