Hi
I am using eppy to run a series of premade IDF files. I have used the code segment described in "Running in parallel processes using Generators." in the eppy documentation. The code segment works perfectly for smaller series of IDF files, but I start getting errors, then I add up to 10000 plus IDF files in the queue. My error right now:

During handling of the above exception, another exception occurred:

But the GlobalGeometryRules are in the IDF files for the given file. Therefore I am inclined to believe the error is occurring. Then I run many IDF files (10000+). Therefore I would be interested if anyone knew how to catch these errors in the Eppy foundation before it crashes my program.
