Problem using fwmark-services

[Matthias Krauss <MKrauss@xxxxxxxxxxxxxx>]

Hi,
i'm having a problem using fwmark-services on a debain sarge box, kernel 
2.6.8-2-386 with ipvsadm 1.2.0,
the connection listing shows:

> pro expire state       source             virtual            destination
> IP  03:38  ERR!        10.0.1.70:0        0.0.0.4:0          10.0.1.30:0
I used the follwoing iptables and ipvsadm command:
/sbin/iptables -t mangle -A PREROUTING -p tcp -s 10.0.0.0/8 \
-d 10.0.1.232/32  --d port 80 -j MARK --set-mark 4
ipvsadm -A -f 4 -s wrr
ipvsadm -a -f 4 -r 10.0.1.33 -g -w 100
ipvsadm -a -f 4 -r 10.0.1.30 -g -w 100

Non marked nodes are working fine, modules looks ok and complete, the 
same script works on on a kernel 2.4.26.
Did anybody came across this ?

Many thanks
Matt.
