Problem with socket() call.

Tony Escujuri — Tue, 31 Jul 2001 17:06:00 GMT

I'm having a strange problem in my application. I'm using the socket(), and it isn't returning a value. It's acting like it's blocking. Has anyone heard of this condition before?

Hi Tony,

I suggest that you post as small a piece of code as possible that exhibits the problem and I suspect someone can then help.

Did you start your app two times? if your app is a server, the new one maybe blocked

If anybody is interested, I've figured out the problem. My program wasn't closing it's file descriptors, and as it ran it reached the maximum number allowed per process. I was using the shutdown() function instead of close(). I thought that the shutdown function closed the filehandle if you closed both the read/write streams, but I was mistaken. Here's the interesting part though. The socket() function didn't return an error reporting this, it just hung there. This appears to be a bug. I've fixed my program so it closes the file descriptors, so it's not a problem. But I'm sure someone else will run into this. Where is the best place to report this?
