STATUS_DATA_OVERWRITTEN
Earlier output may no longer be intact
STATUS_DATA_OVERWRITTEN warns that an operation completed, but data generated earlier may have been replaced before the caller consumed it. This is commonly a sequencing or buffering problem rather than a simple read failure.
Where to look
- Check whether a producer reused a shared buffer before the consumer finished.
- Verify ring-buffer indexes, sequence numbers, and ownership transitions.
- Confirm that asynchronous completions cannot arrive after storage has been recycled.
- Record generation counters so stale data can be detected explicitly.
Recovery
Reissue the operation only when the API guarantees that a retry returns a fresh snapshot. Otherwise, resynchronize with the producer and discard any dependent state built from the overwritten data.
