STATUS_LOG_MULTIPLEXED

STATUS_LOG_MULTIPLEXED indicates an API boundary error: the target is a multiplexed physical log with one or more streams, while the requested operation requires access semantics that CLFS does not permit as a direct physical-log action.

A multiplexed log consolidates records from separate streams into one stable-storage log. It is not interchangeable with a dedicated log merely because both use a base log and containers. Diagnose the log name and stream selector that produced the handle before changing policies or storage.

What to inspect

  • Inspect the original CLFS log name and determine whether it contains a stream component separated by ::.
  • Identify whether the API expects a stream handle or a physical-log handle, then reopen the intended object through the documented path.
  • Keep stream-level tail, archive, and client state separate from physical-log container management.
