Negative connection count in glbd status

[TomiMikola]

After some days of running glbd without problems I'm seeing weird negative connection count values in glbd status info. The backend gives no errors in log output.

[root@glb1 ~]# service glbd status
Router:
------------------------------------------------------
        Address       :   weight   usage    map  conns
      10.1.4.88:3306  :   20.000   0.750    N/A      3
      10.1.4.87:3306  :   10.000   1.250    N/A     -5
      10.1.4.86:3306  :    1.000   0.000    N/A      0
------------------------------------------------------
Destinations: 3, total connections: -2 of 10000 max
[root@glb1 ~]# echo "10.1.4.87:3306:0" | nc 127.0.0.1 4444
Ok
[root@glb1 ~]# service glbd status
