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
