Tornado multi-process startup server reported an error

Hello, everyone. The way I start tornado with socket is as follows:
sockets = tornado.netutil.bind_sockets (options.options.port)
tornado.process.fork_processes (0)
server = HTTPServer (app, xheaders=True)
server.add_sockets (sockets)
try:
ioloop.IOLoop.instance (). Start ()
except KeyboardInterrupt:
ioloop.IOLoop.instance (). Stop ()

The

service starts normally, but I use http request to request an error:

Traceback (most recent call last):
File "manage.py", line 50, in < module >

run()

File "manage.py", line 38, in run

sockets = tornado.netutil.bind_sockets(options.options.port)

File "/ usr/local/lib/python3.5/dist-packages/tornado/netutil.py", line 194, in bind_sockets

sock.bind(sockaddr)

OSError: [Errno 98] Address already in use

could you tell me how to solve it? thank you
