It is non-LoadRunner error like "Error -27728: Step download timeout (999 seconds) has expired when downloading non-resource(s)" or "Connection to load generator failed. Error: Process "lr_bridge.exe" was not created. Reason: - communication error. [MsgId: MERR-29996]", etc. The error means the overlapped operations will complete later.
