ABSTRACT:
In a computer system which allows simultaneous operations of multiple processes, a software watchdog process operates to monitor a primary process through operating system calls. If the response to an operating system call shows that the primary process is not operating or is over utilizing CPU time, then the primary process is restarted. The software watchdog process may also check and correct configuration and data files before restarting the primary process. Alternatively, rather than using operating system calls, the software watchdog process and primary process may communicate through a loop back TCP/IP address for monitoring purposes.
