After they run the spawn, they do a close on the socket id. Is this freeing
the memory or do the IBM examples have a memory leak also?

I've already explained twice in prior messages that I am referring to saving the pid of the child process and passing it to wait() or waitpid() to free up the memory. Surely you can see that this isn't the same thing as closing a socket?!

I don't know which IBM examples you are referring to? The IBM example linked to from the spawn() manual page does indeed do this.

Maybe you'll believe me if you see where IBM mentions this? It uses the term "resources" instead of memory, but it amounts to the same thing. It's on the following page, you have to scroll all the way down to note 15, under "Usage Notes"
