What are the ramifications of calling connect() for an INET Socket Stream repeated times without calling close()? I was sending messages over a socket and immediately called close() after each send session was done. I found my messages were getting lost. When I ran with a breakpoint on my send() the msgs were delivered!

Next I tried the code with a sleep before the close() and that worked too. Not calling close() at all also worked. I don't wait for an ACK msg from the server, it doesn't send one. The server isn't mine so I can't add the ACK response and close the socket after the ACK.

It looks like I can close the socket before the msg is delivered to the server. When this happens the msg gets lost. Is this in fact what is happening?

How should I handle this? I'm probably going to remove the close() call since the connect() and send() happen less than 100 times an hour. Does that sound reasonable?

Thanks in advance.

Update: I'm using Perl 5.6.1 build 631 on Win32. I'm using Socket with tcp and I have output autoflush on.
