Starvation. Stoppage of work of one or several threads of a multithread application for an indefinite (or infinite) period. Threads which are not being scheduled for execution, even if they are not blocked and do not wait, are called starving. The cause of starvation usually lies in scheduling rules and policies. For example, if on a single-core processor we schedule a constantly working non-blocking thread with a high priority, another thread with a lesser priority will never start working.
