2.7.2 Problems that can be detected by the health check function

The health check function can detect the following problems:

• Process hangups

  If a process hangs, the health check function detects the error and notifies the operator. Hangups are caused by an infinite loop or deadlock, and mean that the process can no longer accept processing requests.

• Abnormal termination of a process

  If a process terminates abnormally of its own accord, the health check function detects the error and notifies the operator. However, if the operator forcibly terminates a process by the OS kill command or other means, this is not detected as abnormal termination. Rather, the function detects that there is no response from the process.
