Constant debug logging to /var/log/network/default.log

[Kevin42]

Hello,
I have a TS-231AK with firmware v5.0.1 and I notice that every few seconds it is logging to /var/log/network/default.log and with a lot of DEBUG messages.
How do I disable this log, or at least change the logging level from DEBUG to CRITICAL? I have tried dmseg -n 2 but this had no effect.

I attach an example log, with many lines like this:

complain to qnap..qnap writes logs to all disks constantly (many threads about hdd standby triuble)

[Kevin42]

Some success! I discovered the logging configuration files in:
/usr/local/network/log_config.

By editing all the files to disable DEBUG, INFO and WARN level, and restarting the network services, the logs are much quieter now.

Restart networking with:
# /etc/init.d/network.sh restart.

After the reboot, all files in /usr/local/network/log_config/*.conf are back in their original state.
Does anyone have an idea where I can find the source files for starting qnap in order to edit them?
thx

put your changes in a startup script
