This topic explains the concepts and classification of stability issues, and provides guidance for locating stability issues using system debugging capabilities and tools.
Application stability issues include application crashes, application freezes, and application resource leaks. Performance issues are not classified as stability issues. For details about performance issues, see High-Performance UI Development.
Application crashes, also referred to as unexpected application exits, occur when an application terminates unexpectedly during runtime. They are typically caused by the following factors:
This document focuses on the first two categories: JavaScript crashes and C++ crashes. Other types are covered under application resource leaks and freezes.
When a JavaScript crash occurs, the FaultLogger module collects fault information. For details about how to obtain logs, see Obtaining Logs.
