Stable diffusion webui will be killed when I use controlnet

[hcv1027]

Basic information: GPU: RTX 2070 8G Driver: 531.29 OS: Ubuntu 22.04 run on wsl2

Problem description: As the attached screenshot shows, every time I try to use ControlNet, the web UI is killed after I press the "generate" button. The log only shows the following error message:

Loading model: control_sd15_openpose [fef5e48e]
Loaded state_dict from [/workspace/stable-diffusion-webui/extensions/sd-webui-controlnet/models/control_sd15_openpose.pth]
Killed

However, if I drag an image and click on the "Preview annotator result" button, ControlNet successfully detects the human pose. I have tried reinstalling the application multiple times, but it does not work, and I have no idea what the exact issue is. I hope someone can help me fix this problem. Thank you.

# Turn swap off
# This moves stuff in swap to the main memory and might take several minutes
sudo swapoff -a

# Create an empty swapfile
# Note that "1G" is basically just the unit and count is an integer.
# Together, they define the size. In this case 8GB.
sudo dd if=/dev/zero of=/swapfile bs=1G count=8

# Set the correct permissions
sudo chmod 0600 /swapfile

sudo mkswap /swapfile  # Set up a Linux swap area
sudo swapon /swapfile  # Turn the swap on
