B4J Question [ABMaterial] java.nio.channels.ClosedChannelException

[Anser]

Hi,

When I run the ABM application, I often see the following message in the Log.
Is it something that I can ignore ? Or is it happening for some reason because of my bad coding ?
Any advice will be appreciated

You can most probably ignore it. Such errors happen when the client disconnects from the server while the server is sending data.
