    <br>
    if(!ds_select_dst(...))<br>

            <div>I'm doing stress testing against kamailio (sip load
              balancer role) sending sip registrar, my stress test
              software is sending 50 registrations per second, after 30
              seconds and 1000 registers processed the function
              ds_select_dst (I'm using algorithm 4) returns null for all
              registers sent from my software, and all registrar sip
              servers are available and in active mode, if I reduce the
              software to  send 20 registrar's per second, the issue
              only happens after 60 seconds and kamailio (sip load
              balancer role)  process 4000 registrers, after this,
              function ds_select_dst starts returning null</div>
