Hi,
Thanks for the response...
However, in my case, the Kernel does a
1. sock_sendmsg(... THE REQUEST ...)
2. sock_recvmsg(... THE RESPONSE FROM THE SERVER ...)
I really need the connection open so I can do this in a loop, requesting
various services of the server. When I run the same code in user mode, it
works fine. I have no control over the server (I cant change its code to
close the connection) and also, that is not the protocol in this case.
I would appreciate any advise as I am unfamiliar with these issues.
Sincerely,
Lee

It must be something wrong that I am doing, but once in a while the
following sock_recvmsg hangs for 10 seconds even though the client the
socket is connected to has returned all data...
...
How do I fix this?
Make the server close the socket when it's sent all the data.
The kernel has no idea if "all the data" has been sent until it sees
the close from the sender, but the kernel does use a timeout so that
you do not block forever in MSG_WAITALL if the server does not close
the connection.
Later,
