Aha. That explains it.

That sounds strange - if it was the stats collector, it shuodl be gone.
Verify by running "ps axuwf" (or such) to see if there are two processes
named "stats collector" and "stats bufferer" running. If they are, you
failed to turn them off :-)
If not, it's some other process, try something like "netstat -nap" to
figure out which process is listening for them.
