KEA writes logs, even though it says it's no longer running in GUI

[erdnuesse]

I tried to migrate to KEA, however, I've had some issues so I reverted back, because I didn't get it to run with feature parity, but that's not here nor there.

I Deactivated KEA, with the 90% working config to come back to it later.
I am having another issue currently so my drive was filling up, and I realized I am still collecting KEA logs on a daily basis; 10megs per day, makes 300megs in rotation.

Expected behavior
Deactivation of the service, should maybe not delete old logs, but at least not create new logs. I also don't know currently why KEA is even still running, it's deactivated in the gui, but seems active on cli...

root@kulh4fw1:/var/log/kea # service kea status
DHCPv4 server: active

What's even more confusing to me is my ISC dhcp works, and I did no longer have the migration headaches, so ISC seems to overrule anything KEA still does; but I now reeeeeeally want to delete those logs for my primary issue...
If we need those to debug, I may just collect them, but this is an incident I would like to fix sooner than later.
