A stack overflow error can occur in a computer program due to excessive memory usage. This excessive memory usage occurs on the call stack, which is where information is stored relating to the active subroutines in the program. The call stack has a limited amount of memory available to it. Its size is determined by the programming language, the architecture, whether multi-threading is available on the CPU, and how much memory is available.
Usually, when a stack overflow error occurs, the program crashes and can either freeze or close the program. Any unsaved data or work is lost. The stack overflow error is often caused by an infinite loop, or the creation of variables that are larger than the size of the call stack.
The stack overflow problem is not as prevalent on the newer operating systems, however, because of the small footprint on mobile devices it can become challenging. If your operating system on your mobile device is giving you a stack overflow error you may have too many applications running, a virus is using stack space, or your device has bad hardware. Check your app usage and virus protection and run a memory diagnostic app on your mobile device to see if this helps clear up your error.
