H A Dmonitor_rtapp.rst1 Real-time application monitors
11 Real-time applications may have design flaws such that they experience
12 unexpected latency and fail to meet their time requirements. Often, these flaws
15 - Page faults: A real-time thread may access memory that does not have a
18 action. This causes significant delays to the real-time thread
19 - Priority inversion: A real-time thread blocks waiting for a lower-priority
20 thread. This causes the real-time thread to effectively take on the
21 scheduling priority of the lower-priority thread. For example, the real-time
23 non-pi-mutex, but the mutex is currently owned by a non-real-time thread.
