Kong doesn't stop netcat even when I stop Kong itself

I have a Kong instance where I had reports enabled. So it has netcat process which uses 100% cpu all the time. So I tried to disable anonymous reports, but even then the netcat process doesn’t end.

nc -wl -u kong-hf.mashape.com 61828

From what I read from their docs, this is for sending anonymous syslogs. But I can’t seem to disable it. Has anyone else seen this before?
