Description

The socket doesn't get closed until data hits the socket. The input cannot run because the socket is in use.

#1 Updated by Luke Murphey about 8 years ago

I wish I could find a good way to set the default interval to something like 5 seconds. Setting the interval in the [default] stanza doesn't seem to work.

"The conclusion is that Python sockets should always be closed by first calling shutdown() and then calling close()."

" Even though you've closed your socket, it still has lingering consequences for a couple minutes. The reasons for this, as well as a socket flag you can set to disable the behavior (SO_REUSEADDR), are explained in the UNIX guide socket FAQ."
