[tor-relays] unbound statistics interpretation

[Toralf Förster]

Hi,

at a system shutdown unbound writes the stats in the syslog.

Looking at the stats (pls see below) at a fast relay with 5 days uptime let me wonder about the huge resolving times above the 4 second limit.
Especially I do wonder if there's a parameter to tell unbound to stop a resolving attempt -say- after a minute or so?

I'd appreciate stats of other relay operators.
