Hello Experts,

what does the third column mean?

If you'd listed all the output without filtering with grep you'd see the heading. The second column is Receive-Q and the third is Send-Q. According to man pages these values are:

       The count of bytes not copied by the user program connected to this socket.

       The count of bytes not acknowledged by the remote host.

Thank you KeremE,

here is where I get confused:
the connection is established; then how or why the Send-Q column be so high?
is the remote host accepting a connection but dropping a high percentage of packages?

thanks so much,
