cnfs64 / storage problem

[joey]

Hey there,

i just tested the cnfs64 method and i get a couple of errors..
"googlin'" doesn't solve the prob.

storage.conf
method cnfs64 {
    newsgroups: *.bina*
    class: 1
    options: BIN
}

the BIN is a metacycbuff with ~15GB. Initialization worked, but when
peering is active i get this:

CNFS-sm: no matches for group ''
SERVER cant store article: no rules match

Futhermore the syslog says:

SERVER throttled Success writing SMstore file -- throttling

and the server keeps throttling.

--------------

The controlchan is disabled, and "enableoverview" is set so "false",
because it's just a transit server.

Any hints?

Thanks in advanve,
Johannes
