Did ball bearings in application's garbage collector wear out? As an embedded dev I have thousands of devices that were commissioned and are on 24/7 duty. The oldest still running fleets I believe date back to 2007. Some of them had firmware updates, but many of them (despite numerous bugfixes and improvements since) run on original software. Customers are reluctant to update if there's no specific need arises in their static operational environment. Naturally in business logic world the requirements are never as static. But when they do change you can likely sell the management on it as necessary development.
