Question about RTT

Hi,

I currently use two DCC servers with my SMTP relays.
A 'cdcc info' command reports:

# 11/14/02 10:03:48 CET  /var/dcc/map
# Will re-resolve names after 11:01:15
#   32.97 ms chosen delay  2 total addresses  2 working
IPv6 off

dcc-1,-     xxxxx xxxxxxxx
#   xxx.xx.xxx.xx,-        dcc-1       xxx server-ID xxxx
#      75% of 32 requests ok 1969.89 ms RTT             15 ms queue wait

dcc-2,-     xxxxx xxxxxxxx
# * xxx.xx.xxx.xx,-        dcc-2       xxx server-ID xxxx
#     100% of 32 requests ok    2.19 ms RTT              1 ms queue wait

So, all requests are sent to 'dcc-2' and a few minutes later, servers are inverted, dcc-2
has the lowest RTT! :/

Both servers are on the same LAN and are not overloaded by DCC and/or other traffic.
Any idea?

Xavier
