The warning message indicates that only the changed parameters which are connected to the hardware and applications only downloaded(warm download), It will not disturb the other POU running in the controller.
You can test this by enabling the difference report and observe your changes.
during download controller will copy all the new domain files into the separate memory then it will replace the running application(changed applications only) immediately once it gets downloaded, so while downloading please check the spare memory available to download if system load is high then it may cause opc bad or other communication loss for a few seconds but still it won't stop the process.
No, it should not. The message means that your applications will warm start, even if they have not been changed.
( Of course if there is some problem in warm starting your application, like not retaining variables properly , MMS dropping etc, then these will happen just like any other warmstart )
