Logging of Action Scripts

Hi guys

In our most complex skybow solution so far, we do a lot with actions on buttons.
Some actions are pretty heavy and run for several seconds. For example, at some point we create about 25 new items in a sublist.
Every once in a while, some of the expected items are missing in the sublist.

We tried narrowing down the issue but we never observed such a problem while testing and running with enabled debug-mode.
Everything works just fine over and over again while we watching the process. However, in the productive solution, sometimes items are just missing.
We believe that the action loop suddenly stops while processing.

Is there any option to log the execution of an action-script?
Is there a best practice of such a function? I could imagine, that it would be possible to add an update-item-action after each action in the script to update a log item, but that would of course make the actions-tree more complex to maintain and execution time would significantly increase.

Any ideas on this?!

Best wishes
Dieter
