The "sawtooth" pattern of memory utilization: the sudden drop in used memory is a candidate symptom for a memory leak. If the memory leak is in the kernel, the operating system itself will likely fail. Computers without sophisticated memory management, such as embedded systems, may also completely fail from a persistent memory leak.
Improved memory management and leak removal throughout the entire codebase. CGNS v3.3.0 now distributed and automatically integrated with the autotools build. Additional bug fixes, stability improvements, and general code maintenance.
Many resource leaks are fixed by resource reclamation by the operating system after the process terminates and makes an exit system call. Resource leaks are thus primarily a problem for long-lived processes, as leaked resources held by still-running processes are often not reclaimed; and for processes that rapidly acquire and leak many resources.
User-mode memory dump, also known as minidump, [23] is a memory dump of a single process. It contains selected data records: full or partial (filtered) process memory; list of the threads with their call stacks and state (such as registers or TEB); information about handles to the kernel objects; list of loaded and unloaded libraries.
Graphical user interface for Heimdall running on Ubuntu. Heimdall is a free/libre/open-source, cross-platform replacement for Odin which is based on libusb. [3] Heimdall can be used on Mac or Linux. [10]

Even if a garbage collected programming language is used, resource exhaustion attacks are possible if the program uses memory inefficiently and does not impose limits on the amount of state used when necessary. File descriptor leaks are another common vector. Most general-purpose programming languages require the programmer to explicitly close ...
A handle leak is a type of software bug that occurs when a computer program asks for a handle to a resource but does not free the handle when it is no longer used. [1] If this occurs frequently or repeatedly over an extended period of time, a large number of handles may be marked in-use and thus unavailable, causing performance problems or a ...
