What are you downloading? Is it an object serialized with B4XSerializator?

Thanks for quick reply. As far as I understand, I am not downloading anything. The problem occurs when the application goes background and after 15 to 20 minutes (sometimes) when user wants to rework the application and click on the application to run, it goes white (No back button or other work on that time). When he force to stop the application from background, this error pops up.

Edit - Erel, I have some code to download data from server through DBRequestManager & JRDC2. Let me check whether I need to have any tweak there. Between how can I find in which point the issue may raise, can you please tell? Thank you ...

You can see from the stack trace that it happened in Main.JobDone.
