The OPS connections are accounted in InActConn
for a very short period, they live up to 1 jiffie, eg. 10ms.
Also, WRR should be reliable for OPS while other
schedulers (eg. *LC) are not suitable.

Do you see the same problem with ipvsadm -Ln --stats ?
ipvsadm -Z may be needed to zero the stats after restoring all
rules. "Conns" counter in stats should be according to WRR
weights, it shows the scheduler decisions.
In your rates listing CPS 0 is confusing, even for OPS.
Is it from the new ipvsadm?
