Hola Monks,

I have a few, lets say 4, "sub" processes listening on an IP socket for work.

Since there is always the chance one will crash, what is the best way to tell if they are live?

I could try and connect() to each of them at a fixed interval, but what if they are busy? Since Perl isn't multi-theaded, I assume the socket() call, from the parent, will block...no good.

In the future, I would like to have the "sub" process be on a different machine so checking if the pid is live also doesn't seem like a good solution (I haven't yet tried to find a IsPidLive($pid) fn yet...)

Also, since I am on Win32, and hoping to support Linux in the future, I am not using fork()...

Thanks for any ideas !!!
