Double fault

two unsuccessful serves in a row resulting in the loss of a point (Tennis)

This article is about the CPU error; for the tennis term, see serve (tennis). On the x86 architecture, a double fault exception occurs if the processor encounters a problem while trying to service a pending interrupt or exception.An example situation when a double fault would occur is when an interrupt is triggered but the segment in which the interrupt handler resides is invalid. If the processor encounters a problem when calling the double fault handler, a triple fault is generated and the processor shuts down.As double faults can only happen due to kernel bugs, they are rarely caused by userland programs.
