### Error logs after `raft.shutdown()` completes
**Symptom**: After calling [`Raft::shutdown`][] which returns successfully, logs show
`ERROR openraft::raft::raft_inner: failure sending RaftMsg to RaftCore; message: AppendEntries ... core_result=Err(Stopped)`
**Cause**: Other nodes in the cluster continue sending RPCs to this node. The `Raft` handle still
exists and receives these RPCs, but the internal Raft core has stopped, so forwarding fails.
**Solution**: This is expected behavior. These errors are harmless - they indicate the node has
shut down as requested. You can ignore them or filter these specific error logs after shutdown.
