In, a hang or freeze occurs when either a or system ceases to respond to. A typical example is a that no longer responds to the user's or, but the term covers a wide range of behaviors in both and, and is not limited to issues. Hangs have varied causes and symptoms, including or defects, such as an or long-running uninterruptible computation, resource exhaustion (), under-performing hardware (), external events such as a slow, misconfiguration, and compatibility problems. The fundamental reason is typically resource exhaustion: resources necessary for some part of the system to run are not available, due to being in use by other processes or simply insufficient. Often the cause is an interaction of multiple factors, making 'hang' a loose rather than a technical one. A hang may be temporary if caused by a condition that resolves itself, such as slow hardware, or it may be permanent and require manual intervention, as in the case of a hardware or software logic error. Many modern operating systems provide the user with a means to forcibly terminate a hung program without or; some operating systems, such as those designed for mobile devices, may even do this automatically. In more severe hangs affecting the whole system, the only solution might be to reboot the machine, usually by with an off/on or reset button. A hang differs from a, in which the failure is immediate and unrelated to the responsiveness of inputs. Contents • • • • • Multitasking [ ] In a multitasking operating system, it is possible for an individual or to get stuck, such as blocking on a resource or getting into an infinite loop, though the effect on the overall system varies significantly. In a system, any thread that gets stuck without yielding will hang the system, as it will wedge itself as the running thread and prevent other threads from running. By contrast, modern operating systems primarily use, such as ///, 's and. In these cases a single thread getting stuck will not necessarily hang the system, as the operating system will preempt it when its time slice expires, allowing another thread to run. If a thread does hang, the scheduler may switch to another group of interdependent tasks so that all processes will not hang. However, a stuck thread will still consume resources: at least an entry in scheduling, and if it is running (for instance, stuck in an infinite loop), it will consume processor cycles and power when it is scheduled, slowing the system though it does not hang it. However, even with preemptive multitasking, a system can hang, and a misbehaved or malicious task can hang the system, primarily by monopolizing some other resource, such as IO or memory, even though processor time can't be monopolized. For example, a process that blocks the file system will often hang the system. Causes [ ] can cause a computer to hang, either because it is intermittent or because it is mismatched with other hardware in the computer (this can occur when one makes an ). Hardware can also become defective over time due to dirt or heat damage. A hang can also occur due to the fact that the programmer has incorrect termination conditions for a, or, in a, forgetting to yield to other tasks. Said differently, many -related hangs are caused by waiting for an event to occur which will never occur. This is also known as an. Another cause of hangs is a in communication between.
