select.error: (4, 'Interrupted system call')

Hi

I want to use websocket for Automatic Speech Recognition (ASR) server side. I try to load models in __init__. After the models loaded successfully,the following exception thrown out:

Selected GPU[0] GeForce GTX 1060 6GB as the process wide default device.
ASR model loaded successfully
(('127.0.01', 56236), 'connected')
Traceback (most recent call last):
File "websocket_server2.py", line 111, in
server.serveforever()
File "/home/aj/anaconda3/envs/cntk-py27/lib/python2.7/site-packages/SimpleWebSocketServer/SimpleWebSocketServer.py", line 677, in serveforever
self.serveonce()
File "/home/aj/anaconda3/envs/cntk-py27/lib/python2.7/site-packages/SimpleWebSocketServer/SimpleWebSocketServer.py", line 618, in serveonce
rList, wList, xList = select(self.listeners, writers, self.listeners, self.selectInterval)
select.error: (4, 'Interrupted system call')

My class defined as bellow:

# -*- coding: utf-8 -*-
from SimpleWebSocketServer import SimpleWebSocketServer, WebSocket
from ASR import ASR


class SimpleEcho(WebSocket):

    def __init__(self, server, sock, address):
        super(SimpleEcho, self).__init__(server, sock, address)
        self.asr = ASR()

    def handleMessage(self):
        data = np.frombuffer(self.data, 'i2')
        result = self.asr(data)
        self.sendMessage(unicode(result))

    def handleConnected(self):
        print(self.address, 'connected')
        self.sendMessage(unicode('connection stablished...'))

    def handleClose(self):
        print(self.address, 'connection closed')
        self.sendMessage(unicode('connection closed...'))

server = SimpleWebSocketServer('0.0.0.0', 8081, SimpleEcho)
server.serveforever()

What cause such exception and how can I avoid it?
regards.
