[OpenSIPS-Devel] Load Balancer - not balancing and double counting

[Bogdan-Andrei Iancu]

Hi Alec,

Indeed, thanks to the extra info you sent me I manage to discover a bug 
in the new code for LB failover (in removing the dialog from the failed 
profile).

Please update from SVN and it should work now.

Thanks and Regards,
Bogdan
