Process automatic restoring method

The present invention provides an automatic recovery method for process. It uses the process must be monitored as father process, said father process can be used for producing several subprocesses, the several subprocesses are set into a working group process, and said father process can be used for monitoring the abnormality of subprocess in the working group by means of exchange semaphore module, and can make the subprocess be exited from the working group and can produce a group of subprocess again as working group process so as to implement the automatic recovery of the process.
