Maybe LXD has some resource issue here. I see the file descriptor error in screenshot. Can you check if it’s a LXD container issue and not COOLWsd problem…
If coolwsd is running inside an LXD container:
- File Descriptor Limit: Ensure the container has sufficient file descriptors:
ulimit -n 65535
AppArmor Profiles: Check if AppArmor is blocking the process:
sudo aa-status
- If coolwsd appears under profiles in enforce mode, you may need to adjust or disable the profile.
