In computer science, resource starvation is a problem encountered in concurrent computing where a process is perpetually denied necessary resources to process its work. [1] Starvation may be caused by errors in a scheduling or mutual exclusion algorithm, but can also be caused by resource leaks , and can be intentionally caused via a denial-of ...
Like shortest job next, it has the potential for process starvation: long processes may be held off indefinitely if short processes are continually added. [1] This threat can be minimal when process times follow a heavy-tailed distribution. [2]

In computer science for Operating systems, aging (US English) or ageing is a scheduling technique used to avoid starvation. Fixed priority scheduling is a scheduling discipline, in which tasks queued for utilizing a system resource are assigned a priority each. A task with a high priority is allowed to access a specific system resource before a ...
Shortest job next is advantageous because of its simplicity and because it minimizes the average amount of time each process has to wait until its execution is complete. However, it has the potential for process starvation for processes which will require a long time to complete if short processes are continually added.

In terms of concurrent programming, a buffer underrun can be considered a form of resource starvation. The term as defined above is distinct from buffer overflow, a condition where a portion of memory forms a buffer of a fixed size yet is filled with more than that amount of data, thus overwriting memory locations outside of the allocated chunk.
