Aws-iot-device-sdk-python-v2: AWS_ERROR_MQTT_UNEXPECTED_HANGUP अनंत पुन: कनेक्शन लूप

यह सुनिश्चित करने के लिए कि यह एक बग है, नीचे [ ] को [x] में बदलकर पुष्टि करें:

• [x] मैंने पिछले समान मुद्दों की खोज की है और कोई समाधान नहीं मिला

ज्ञात मुद्दा

• [x] मैं एटीएस डेटा प्रकार एंडपॉइंट का उपयोग कर रहा हूं: एंडपॉइंट <prefix>-ats.iot.<region>.amazonaws.com जैसा दिखना चाहिए

हाय एडब्ल्यूएस टीम,

हम 2 दिनों से एसडीके के साथ एक महत्वपूर्ण समस्या का सामना कर रहे हैं (विवरण नीचे)।

बग का वर्णन करें
होस्ट रिज़ॉल्यूशन के तुरंत बाद टास्क-शेड्यूलर द्वारा TLS चैनल शटडाउन जिसके परिणामस्वरूप अनंत RECONNECTING <> AWS_ERROR_MQTT_UNEXPECTED_HANGUP लूप (बहुत सारा डेटा खा रहा है !!)
एंडपॉइंट से एसडीके कनेक्शन कभी स्थापित नहीं होता है। टीएलएस बहुत तेज गति से सत्र के उद्घाटन और समापन के कारण जबरदस्त डेटा उपयोग फट गया (अचानक समस्या के कारण हमें एक फील्ड डिवाइस पर कई सौ डॉलर का डेटा रोमिंग बिल मिला)।

एसडीके संस्करण संख्या
प्रत्येक मामले में 1.5.12 और 1.5.14 और मिलान aws-crt के साथ परीक्षण किया गया

प्लेटफार्म/ओएस/डिवाइस
आर्महफ डिवाइस (कॉर्टेक्स-ए 7)
ubuntu 20.04 . पर आधारित डॉकर कंटेनर

पुन: उत्पन्न करने के लिए (मनाया व्यवहार)

एसडीके का मानक उपयोग देखा गया था और पुन: कनेक्शन लूप होने से पहले डिवाइस 10 दिनों तक चल रहा था। उसके बाद, डिवाइस कभी भी हमारे एंडपॉइंट से ठीक से दोबारा कनेक्ट नहीं हो पाया और रीकनेक्शन लूप हमेशा मौजूद रहेगा। सामान्य ऑपरेशन के 10 दिनों के बाद 30.04.2021 को व्यवहार बदल गया (कनेक्शन और हर 3 मिनट में प्रकाशित)। प्रमाणपत्र और सीए की समय सीमा समाप्त नहीं हुई है और नए प्रमाणपत्र के तहत नवीनीकृत डिवाइस पंजीकरण से मदद नहीं मिली है। एसडीके 1.5.12 से 1.15.14 तक अपडेट ने भी मदद नहीं की।

AWS_KEEP_ALIVE_SECS = 30

    # setup AWS connection
    io.init_logging(io.LogLevel.Debug, 'stderr')
    event_loop_group = io.EventLoopGroup(1)
    host_resolver = io.DefaultHostResolver(event_loop_group)
    client_bootstrap = io.ClientBootstrap(event_loop_group, host_resolver)

    client_id = "auto-%s" % str(uuid.uuid4()).upper()
    aws_mqtt = mqtt_connection_builder.mtls_from_path(
        endpoint=args.endpoint,
        cert_filepath="%s/device.crt" % (args.provision_location),
        pri_key_filepath="%s/device.key" % (args.provision_location),
        client_bootstrap=client_bootstrap,
        ca_filepath="%s/AmazonRootCA1.pem" % (args.cert_location),
        on_connection_interrupted=aws_on_connection_interrupted,
        on_connection_resumed=aws_on_connection_resumed,z
        client_id=client_id,
        clean_session=False,
        keep_alive_secs=AWS_KEEP_ALIVE_SECS)

अपेक्षित् व्यवहार

कोई अप्रत्याशित हैंगअप नहीं। और कोई अनंत पुन: कनेक्शन लूप नहीं।

लॉग/आउटपुट

नेटवर्क उपयोग के कारण एक परिनियोजित रोमिंग डिवाइस (16GB) पर कई GB का सिम डेटा उपयोग होता है। यहाँ एक eth0 आधारित कनेक्शन प्रयास पर नेटवर्क डेटा उपयोग है:
