> The router tries to make a raw socket connection to an nginx server on port 
> 80 but that nginx server is not running. The raw socket connection fails (as 
> expected). I see a PN_RAW_CONNECTION_DISCONNECTED event (also expected). But 
> I see  PN_RAW_CONNECTION_NEED_WRITE_BUFFERS and 
> PN_RAW_CONNECTION_NEED_READ_BUFFERS events *after* the 
> PN_RAW_CONNECTION_DISCONNECTED event as seen below in the log  -

> 2020-09-23 11:22:40.006792 -0400 HTTP_ADAPTOR (trace) [C1] 
> PN_RAW_CONNECTION_NEED_WRITE_BUFFERS Need write buffers

> PN_RAW_CONNECTION_NEED_READ_BUFFERS Need read buffers {noformat}

> The documentation on pn_raw_connection_close() seems to suggest that 
> PN_RAW_CONNECTION_DISCONNECTED will be the very last event emitted on a 
> connection.
