Shutting down the server with ctrl+c hanging with docker image

[manickavela29]

Running seldon-sore in Docker image, but when I do ctrl+c,
it is hanging as in the below code :

^C[2024-08-02 14:04:09 +0000] [1] [INFO] Handling signal: int

have to manually terminate the container everytime to get out of this situation

To reproduce

Docker file

FROM nvidia/cuda:12.0.0-cudnn8-devel-ubuntu20.04

RUN apt-get update && \
    apt-get upgrade -y && \
    apt-get install -y --no-install-recommends python3 python3-pip && \
    rm -rf /var/lib/apt/lists/*

# nvidia-container-toolkit-base

RUN ln -s /usr/bin/python3 /usr/bin/python

WORKDIR /app

# Install python packagess
COPY requirements.txt requirements.txt
RUN python3 -m pip install -r requirements.txt

RUN python3 -m pip install prometheus-client==0.20.0 pydantic==2.8.2
RUN pip install flash-attn --no-build-isolation
# Copy source code
COPY . .

# Port for GRPC
EXPOSE 8081
# Port for REST
EXPOSE 8080

ENV MODEL_NAME <Project py fail and class name>
ENV SERVICE_TYPE MODEL
ENV API_TYPE REST
ENV PERSISTENCE 0
ENV HF_HOME /app/.cache/
ENV USE_MULTIPROCESS_PACKAGE true
ENV MODEL_PATH /app/models/<project py file>

# Changing folder to default user
RUN chown -R 8888 /app
RUN mkdir -p /app/.cache
RUN chown -R 8888 /app/.cache
RUN mkdir -p /app/model
RUN chown -R 8888 /app/model

CMD exec seldon-core-microservice $MODEL_NAME --service-type $SERVICE_TYPE

Functionally server is up and running sucessfully,
everything is good,
only ctrl+c it is happening

Running Laama 3 8b (but irrelevant in my case)
