ERROR_COM_TASK_STOP_PENDING
The COM task is still stopping
ERROR_COM_TASK_STOP_PENDING reports an asynchronous lifecycle state: stop processing is underway, so a conflicting start, shutdown, or reconfiguration request cannot yet complete.
Typical handling
- Wait for the documented completion notification.
- Prevent duplicate stop requests from racing each other.
- Use a bounded shutdown timeout and record outstanding work.
- Do not release shared resources until the task confirms it has stopped.
Diagnosis
If the state persists, capture thread stacks, pending COM calls, cancellation state, and the component responsible for completion. Retrying the same command rapidly can hide the original hang and amplify contention.
Lifecycle state machine
Model running, stop-requested, stopping, and stopped as distinct states. New work should be rejected or queued once stopping begins, while cleanup callbacks remain allowed to finish.
Hung-stop investigation
Record the task identifier, stop request time, outstanding COM calls, cancellation tokens, and owner thread. A dump taken after the timeout is often more useful than repeated stop commands that alter the evidence.
