[OpenSIPS-Users] Load balancer probe _mode=1 bug?

[Bogdan-Andrei Iancu]

Hi Bill,

What is the probing interval you configured ?
       
http://www.opensips.org/html/docs/modules/1.6.x/load_balancer.html#id250040

Could you test the attached patch ? (same as revision 7356 on trunk).

Regards,
Bogdan
