InBPS rate statistics wrong? (for fwmark service)

[Mark de Vries <markdv.lvsuser@xxxxxxxxxx>]

Just testing using fwmark services and noticed that even when no packets
are hitting the service ipvsadm -L --rate keeps showing InBPS > 0.

I have a single itables rule marking packets (with '10').

iptables -t mangle -xnvL has shown a constant of 103 packets having hit
the rule for hours... Yet ipvsadm -L -f 10 --rate shows:

Prot LocalAddress:Port     CPS    InPPS   OutPPS    InBPS   OutBPS
  -> RemoteAddress:Port
FWM  10                      0        3        0      182        0
  -> cns3:domain             0        0        0       30        0
  -> cns2:domain             0        0        0        0        0
  -> cns1:domain             0        1        0       53        0
  -> cns0:domain             0        2        0       98        0

If no packets have been marked for hours how can this be?

Mark.
