Underflow in Stats Channel RecursClients value?
Summary
It looks like we may have an underflow condition in the Stats Channel RecursClients value
BIND version used
Reported by a customer using 9.11.7-S1
What is the current bug behavior?
A customer who is using the statistics channel to monitor BIND behavior tells us:
Hello,
We have our DNS servers configured to collect stats. We have metrics servers collect the data so it can be displayed.
The data for the RecursClients stat randomly is a very high number. See below.
This is happening on a number of my servers.
name="RecursClients">18446744073709551440
name="RecursClients">18446744073709551426
From another server.
name="RecursClients">18446744073709551518
When I do an "rndc reconfig" the counter will clear out. But in a few seconds it will jump back up.
What is the expected correct behavior?
Obviously the customer does not actually have on the order of 2 ^ 64 recursive clients.
