Serdar, Have you tried to clean variables before calling new ds_select_domain(), that are using by dispatcher module failover? Like https://kamailio.org/docs/modules/5.3.x/modules/dispatcher.html#dispatcher.… and so on? But as I got, you're saying, that calling ds_select_domain() with different setid's in a case of fail, not really fails, but using "old" available destinations from previous attempt?
