It shouldn’t, but with SmartThings who knows?
Normally the messages are just telling you about a problem that exists whether you run the repair or not.
“Failed to update the mesh” could just mean a sleepy device that was asleep when the message went out.
But there’s a huge difference between getting this particular error message with the device name and getting it just with an ID. If you get it just with an ID number, you have some ghost devices and you do need to clean that up. See the following thread for details on the error messages.
