Unfortunately, there's too much customer specific code in this project to upload it. Also, the project is targeted to a board that has unusual peripherals: it probably won't run without serious modification. I will attempt to make a project using the Rigado BMD-300 that exhibits this behavior and upload that.

Also, I am not convinced that I am using FreeRTOS correctly. This could be the problem.

Can you tell me why power consumption and simultaneous signal transition in are specifically noted in this post (see answer #1)? When I read this it implies that simultaneous signal transitions using PORT events are not supported.

Thanks for your time,

ACV

OK, lets keep FreeRTOS out of this as it seems it has nothing to do with the problem. The low accuracy thing says whether to use PORT interrupt or IN EVENTS interrupt. Since you are using low_accuracy, it uses port interrupts. It should not technically matter if one pin has changed or all pins has changes simultaneously to trigger the PORT event. I am not sure why GPIOTE stops responding in such a situation. I do not think that GPIOTE hardware have any problems, could be a driver issue. Can you upload your project so that i can reproduce your issue?
