There are many reasons, one is that you may be sending data that hasn't been ack'd and might need retransmition. There may also be a lot of data 'in flight' meaning that one reading data from the network and the reader is slower than the writer which keeps mbufs tied down in the socket buffers. -- -Alfred Perlstein - [bright@wintelcom.net|alfred@freebsd.org] "I have the heart of a child; I keep it in a jar on my desk."
