How to catch undocumented industry errors?

[Verliezer]

Is there a way to capture industry errors like "Unknown Error" in your industry?

There are a few errors which are worthwhile getting notifications on, but which aren't officially documented. Maybe there is a "other then known" category?

As far as I know, it is not currently possible to directly distinguish the unknown error status for industry units using the standard lua functions. This functionality has been requested a few times but I suspect the emphasis would instead be on eliminating scenarios where such an error were to occur. However some lua coders have cleverly gotten around this by monitoring the time it takes for a given recipe to complete and subsequently infer a server error has occurred if the reported state is still reported as "running" past the point where it should have completed.
