<p>Running Kamailio 4.2.3. When the UAC module sends a registration request, it sets the UAC_REG_ONGOING flag in reg->flags. If there is no response to the request, the flag is never cleared, so all future calls to uac_reg_update return without ever retrying the request. That is, the registration becomes "stuck" in the UAC_REG_ONGOING state forever.</p>
