PLA_E_DCS_IN_USE
The persisted definition and the active collection instance have separate lifetimes
PLA_E_DCS_IN_USE means an operation requires exclusive access while the Data Collector Set, an ETW session, a collector, or a Data Manager task is still active. The set may appear stopped in one client while asynchronous shutdown or report processing continues elsewhere.
Query the set status and identify dependent trace-session names before changing or deleting the definition. Wait for collectors to finish flushing, reports to close their inputs, and scheduled tasks to release output files. Creating a second COM object does not create a second independent set; both objects can refer to the same persisted configuration and runtime resources.
Ownership evidence to inspect
- Current IDataCollectorSet status and last transition.
- Active ETW sessions associated with trace collectors.
- Report or folder actions still processing output.
- Processes holding the set definition or log files.
