Obviously... The hello runs as independent FastCGI Server and if it crashes it crashes
like any other program. I though you told me that "web server" crashes, but hello.exe
is not web server.


If you want hello.exe to be restarted you need to do it on your own
(at least on Windows that does not support fork() system call).
Simple bat script can do this for you.


You can also configure the web server to control the life time of the "hello.exe",
start it, shut it down or restart.

This is what described in the link below.

Thus apache would restart CppCMS service when it crashes for you.


AFAIK there are users that run CppCMS this on Windows with Apache that is controlled by Apache
and I even get patches for graceful shutdown by apache support.
