cdcc info and rtt don't query all servers in the map

Below is the output of 'cdcc rtt' from one of our mailservers, running 
dccifd,
with passwords removed.

Note that cdcc claims that dcc1.dcc.xs4all.nl was 'not answering' at 
this time. It most definitely was. A tcpdump of traffic to or from 
194.109.22.195 from the host that this command was run on, shows no 
packets being sent to that server at all. A random check indicates that 
more of our dcc client installations exhibit this behaviour, although 
apparently not all.

Is that intended behaviour? Does this not cause that last server to 
never be picked by the client as the server to send it's reports to?

Thanks,

Vincent.
