memory leak

This term is a technical compound noun used primarily in software engineering and computer science. It describes a specific type of resource mismanagement where memory is allocated but never freed, leading to a gradual depletion of available system resources. The connotation is almost always negative, as it implies a bug or a flaw in the code's logic.

In a professional context, it is often contrasted with a "crash" or "segmentation fault." While a crash is an immediate failure, a memory leak is a slow degradation of performance. It is typically discussed in the context of long-running processes, such as servers or operating systems, where the cumulative effect of the leak becomes critical over time.
