[lvs-users] LVS-DR/ipvsadm displaying incorrect ActiveConn for custom TC

All,

I'm running a custom TCP service on port 80 which fields byterange
requests to clients. When running LVS-DR with WLC scheduling, an
ipvsadm -L -n displays seemingly incorrect ActiveConn counts. When
loading the server with 500 clients I will only see a dozen at best
ActiveConn entries. This leads me to believe that WLC may not be
working correctly, or may be scheduling clients incorrectly.

Config excerpts:

ldirectord.cf:
quiescent=yes
virtual=x.x.x.1:80
       real=x.x.x.2:80 gate
       real=x.x.x.3:80 gate
       fallback=127.0.0.1:80 gate
       scheduler=wlc
       persistent=600
       netmask=255.255.255.255
       protocol=tcp
       checktype=ping
       failurecount=3

Testing using RR scheduling works as advertised and I can confirm that
the DR is indeed working from parsing the server logs being generated
for connection requests.

Perhaps it is a misunderstanding of the connection state related to
ActiveConn on my part, or something else. Any pointers are
appreciated.

Cheers
Kon
