[ratelimits] rpz add_nm Warnings

[Thomas Leuxner]

Hi,

as of 'BIND 9.9.3-rpz2+rl.13214.22-P2' I'm getting a lot of these after zone transfers:

Aug 25 10:13:22 spectre named[29760]: transfer of 'rpz.spamhaus.org/IN/internal' from 199.168.90.51#53: connected using 188.138.3.245#45302
Aug 25 10:13:22 spectre named[29760]: rpz add_nm(micelich.biz): bits already set
Aug 25 10:13:22 spectre named[29760]: rpz add_nm(micelich.biz): bits already set
[...]

I'm confused what the 'bits already set' message ought to tell me.

Regards
Thomas
