Causes of starvation

With the complexity of designing a scheduling algorithm in mind, let us discuss the specific causes of starvation. The situations that we described in the preceding section indicate some potential causes of the situation of starvation. However, starvation can arise from a number of sources, as follows:

• Processes (or threads) with high priorities dominate the execution flow in the CPU, and hence, low-priority processes (or threads) are not given the opportunity to execute their own instructions.
• Processes (or threads) with high priorities dominate the usage of non-shareable resources, and hence, low-priority processes (or threads) are not given the opportunity to execute their own instructions. This situation is similar ...
