    摘要： A software implementation of an application watchdog, comprising a restart service operating in the user mode and a watchdog driver operating in the kernel mode of a computer operating system. The driver incorporates a system thread configured to monitor a plurality of user applications operating in the user mode. The driver provides a first IOCTL signal interface for communicating control signals between the watchdog driver and one of the user applications and a second IOCTL signal interface for communicating control signals between the watchdog driver and the restart service. A communication interface exists for coordinating timer events with the operating system scheduler. If the system thread does not receive a message from one of said applications within an allotted period of time, the timer event alerts the watchdog driver that the allotted time has elapsed and the watchdog driver signals the restart service to restart that application.

    摘要： A system and technique for detecting and classifying data errors in a memory device. More specifically, data errors in a memory device are detected by a host controller. The error is classified as a hard error or a soft error. If the error is classified as a hard error, a tracking device is implemented to track the number of hard errors detected in the system. Once a pre-determined number of hard errors are detected in a particular memory segment, an indicator, such as a light emitting diode (LED), may be used to indicate the corresponding memory segment should be replaced.
