If you close the browser window, processing threads continue in the background

You perform an action or make a selection and immediately close the browser window. You expect that processing terminated but the messages stored in the messages.log file show that processing continued in the background.

Cause and solution:

This is normal behavior for any WEB application, when the client browser is closed no notification is delivered to the server according to the HTTP protocol specifications. This is the reason why the last triggered thread continues to process even after the browser window was closed. You do not need to run any action, just allow the thread to end.
