Break in MQTT connection silently crashes Deepstream pipeline

Accelerated Computing Intelligent Video Analytics DeepStream SDK

• Hardware Platform (Jetson / GPU): Jetson
• DeepStream Version: 7.1
• JetPack Version (valid for Jetson only) 6.1
• TensorRT Version 10.3.0
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs) Bug
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)

Here are some details about my setup:

  • The Deepstream pipeline is running on a NVIDIA Jetson Orin NX (16GB) device inside the nvcr.io/nvidia/deepstream-l4t:7.1-triton-multiarch Docker container.

  • I’ve configured the nvmsgbroker to send messages out of the Deepstream container using the Python plugins

msgbroker = Gst.ElementFactory.make("nvmsgbroker", "nvmsg-broker")
msgbroker.set_property('sync', 0)
msgbroker.set_property('new-api', 1)
  • The Mosquitto service is managed outside this Docker environment

• Bug Description

These are what my logs look like:

As you can see from the log messages (and timestamps) above the Deepstream pipeline crashes about 30 seconds after the Mosquitto service restarts/stops.

I need your support to make the nvmsgbroker element robust to these breaks in connection.
I further examined the code in /opt/nvidia/deepstream/deepstream/sources/gst-plugins/gst-nvmsgbroker and found that there is no mechanism for reconnecting back to the Mosquitto service.
Here I’m specifically referring to the empty nvds_msgapi_connect_callback method in /opt/nvidia/deepstream/deepstream/sources/gst-plugins/gst-nvmsgbroker/gstnvmsgbroker.cpp

static void
nvds_msgapi_connect_callback (NvDsMsgApiHandle h_ptr,
    NvDsMsgApiEventType ds_evt)
{

}

  1. which MQTT version are you using? How did you restart MQTT server? which sample are you referring to?
 lvt-deepstream  | Error disconnecting: (The client is not currently connected.).
 lvt-deepstream  | mqtt connection success; ready to send data
  1. from your log, the client reconnected successfully, but it did not send data again after 2025-02-05T15:53:46.
  2. Using mosquitto-2.0.15, I tested with deepstream-test5, after restarting(ctrl+c, then mosquitto -v), the test5 did not crash or exit. it just did not send data. could you confirm if the client crashed? From server side, the server printed “Client uniqueID already connected, closing old connection.” repeatedly .

  1. which MQTT version are you using?
    2.0.20
  2. How did you restart MQTT server?
systemctl restart mosquitto

  1. which sample are you referring to?
    I’m using a custom pipeline that looks like this

    pipeline
    pipeline13345×533 307 KB

  2. from your log, the client reconnected successfully, but it did not send data again after 2025-02-05T15:53:46.5.
    I’ve added more context in 5. See more logs below

    Here are some more logs that can help describe the issue better. I’ve also added logs from Mosquitto service

Here is a workaround.
from the server log, the server will disconnect if reconencting with the same client-id.
if config is set for nvmsgbroker, please comment out “client-id =…” in “config” file.

That worked. Thanks!
Are there any plans to fix this in the future?

Thanks for the update! We will discuss it internally then get back to you.

@fanzh Your suggestion fixed a part of the issue but I’m still seeing the same error being thrown when the MQTT Broker restarts. The error being Error sending repeat publish: The client is not currently connected. from /opt/nvidia/deepstream/deepstream-7.1/sources/libs/mqtt_protocol_adaptor/nvds_mqtt_proto.cpp file.

Do you have a fix that is more robust to these connection breaks?

From the logs, the cleint succeeded to reconnect after restarting the MQTT server, but no data was sent. we are investigating.
