WebAug 18, 2004 · Priority inversion occurs in concurrent programs when low-priority threads hold shared resources needed by some high-priority thread, causing them to block indefinitely. Shared resources are usually guarded by low-level synchronization primitives such as mutual-exclusion locks, semaphores, or monitors. There are two existing … Webmay come to a halt or even break down. Reducing or eliminating priority inversion results in improved stability and performance. A well known solution to priority inversion is priority inheritance [4]. Unfortunately, priority inheritance is neither built‐in in windows XP nor in Ada.
