Real Server not balancing to the backup server

[Xavier Mertens <xavier@xxxxxxxxxxxxxx>]

Hi,

I've the following config:

RealServer (Linux box 2.2.16-22) with two nodes configured to reveive
RADIUS traffic. Weight are set to force a kind of fail over:

UDP  radius-vs:rad-auth rr
  -> hades:rad-auth Route   1      0          1
  -> virgo:rad-auth Route   65535  0          0
UDP  radius-vs:rad-acct rr
  -> hades:rad-acct Route   1      0          1
  -> virgo:rad-acct Route   65535  0          0

I wrote a small daemon which monitors the 2 RADIUS servers and issues
"ipvsadm -(a|d)" in case of troubles with one of the RADIUS.

Problem: once the daemon removed the node "hades" (weight 1), the traffic
is NOT forwarded to virgo (weight 65535)! Any idea? If a few minutes later,
hades is back, the traffic is still send to this host.

Regards,
Xavier
