DLL Hell. In computing, DLL hell is a term for the complications that arise when one works with dynamic-link libraries (DLLs) used with Microsoft Windows operating systems, [1] particularly legacy 16-bit editions, which all run in a single memory space. DLL hell can manifest itself in many different ways wherein applications neither launch nor ...
In computing, a segmentation fault (often shortened to segfault) or access violation is a fault, or failure condition, raised by hardware with memory protection, notifying an operating system (OS) the software has attempted to access a restricted area of memory (a memory access violation). On standard x86 computers, this is a form of general ...
Memory used in desktop computers is usually neither, for economy. However, unbuffered (not-registered) ECC memory is available, [34] and some non-server motherboards support ECC functionality of such modules when used with a CPU that supports ECC. [35] Registered memory does not work reliably in motherboards without buffering circuitry, and ...
It records memory errors, using the EDAC tracing events. EDAC is a Linux kernel subsystem that handles detection of ECC errors from memory controllers for most chipsets on i386 and x86_64 architectures. EDAC drivers for other architectures like arm also exists.
Memory corruption occurs in a computer program when the contents of a memory location are modified due to programmatic behavior that exceeds the intention of the original programmer or program/language constructs; this is termed as violation of memory safety. The most likely causes of memory corruption are programming errors (software bugs).
A general protection fault (GPF) in the x86 instruction set architectures (ISAs) is a fault (a type of interrupt) initiated by ISA-defined protection mechanisms in response to an access violation caused by some running code, either in the kernel or a user program. The mechanism is first described in Intel manuals and datasheets for the Intel ...
PCI hole. The PCI hole or PCI memory hole is a limitation of 32-bit hardware and 32-bit operating systems that causes a computer to appear to have less memory available than is physically installed. [1] This memory addressing limitation and the later workarounds necessary to overcome it are functionally similar to the memory limits of the early ...
These locations can become vulnerable to more than one soft error, while scrubbing ensures the checking of the whole memory within a guaranteed time. On some systems, not only the main memory (DRAM-based) is capable of scrubbing but also the CPU caches (SRAM-based). On most systems the scrubbing rates for both can be set independently.
