Triton Server Crash with Signal (11) with Async BLS

AbelDR commented 11 months ago

Description Triton Sever crashed after some period of time running inferences using Python Backend models. The Python backend models are running TensorRT models with mmdeploy python api .

Triton Information Triton Version = 2.40.0 Triton Container Version = 23.11

Are you using the Triton container or did you build it yourself? Built by compose.py

python3 compose.py --backend python --container-version 23.11

To Reproduce We are running two python models with BLS, the first one pre-process the image, and the other running an OCR pipeline (Detection+Recognition) . The Golang client is using sync gprc request to send an input image along with json structured data.

Preprocessing model pbtxt:

backend: "python"
parameters: {
    key: "EXECUTION_ENV_PATH"
    value: {string_value: "/ksim/anaconda3/envs/cvcuda"}
}
max_batch_size: 0
input [
    {
        name: "IMAGE_IN"
        data_type: TYPE_UINT8
        format: FORMAT_NHWC
        dims: [ -1, -1, 3 ]
    },
    {
        name: "RULES"
        data_type: TYPE_UINT8
        dims: [ -1 ]
    }

]
output [
    {
        name: "OUTPUT0"
        data_type: TYPE_STRING
        dims: [ -1 ]
    }
]

OCR Pipeline model pbtxt:

backend: "python"
parameters: {
    key: "EXECUTION_ENV_PATH"
    value: {string_value: "/ksim/anaconda3/envs/cvcuda"}
}
max_batch_size: 0
input [
    {
        name: "INPUT0"
        data_type: TYPE_UINT8
        format: FORMAT_NHWC
        dims: [ -1, -1, 3 ]
    },
    {
        name: "RULES"
        data_type: TYPE_UINT8
        dims: [ -1 ]
    }
]
output [
    {
        name: "OUTPUT0"
        data_type: TYPE_UINT8
        dims: [ 1]
    },
    {
        name: "OUTPUT1"
        data_type: TYPE_STRING
        dims: [ -1]
    }
]
instance_group [
    {
      count: 1
      kind: KIND_GPU
    }
]`

Crash logs

This stress test started at 01:00 am to 06:53 am with a total of 250K inferences approximately. We got the same problem with different number of inferences and period of time. In the past, this problem didn't happen using Triton 22.12. We update Triton to improve robustness and reliability.

Expected behavior We are expecting a robust inference sever that don't crash long runs.

PauloFavero commented 11 months ago

I'am also experiencing this issue after upgrading Triton. Our team is using Triton in a production environment and it's having a huge impact in our product.

tanmayv25 commented 11 months ago

We have made a couple of fixes in r23.12 version in python backend concerning BLS pipeline. See here: https://github.com/triton-inference-server/python_backend/commits/r23.12/ Can you verify if the issue is reproducible with 23.12 release?

We tested the new version r23.12 and the same problem occurred. I made some tests avoiding to use BLS async models converting them to BLS sync models and work without problems. Now, in this way, we have a time inference problem.
In the past (Triton r21.09) we used BLS async models without problems, but now we have to used the last Triton stable version.

Thanks in advance!

tanmayv25 commented 10 months ago

Can you share the simple reproducer model repository and client that we can use?

AbelDR commented 10 months ago

Yes, sure! Monitoring docker stats, Triton crashes even without memory overflow problem. We tested Triton server + client in: Corei7 12th + RTX3060 + 16GB
