pjsip_udp_transport_restart seems to have a race condition in 1.10.
When called as:
??????????????? status = pjsip_udp_transport_restart(
?????????????????????????? tp,
??????????????????????????? PJSIP_UDP_TRANSPORT_DESTROY_SOCKET,
??????????????????????????? PJ_INVALID_SOCKET,
??????????????????????????? &saddr,
??????????????????????????? &a_name) ;
I get intermittent failures of the socket bind in create_socket, failing with EADDRINUSE.
If I add a sleep and loop retry around the bind, it will succeed eventually.
I theorize that this implicit close code in? pjsip_udp_transport_restart:
??????? if (tp->key) {
??????????? /* This implicitly closes the socket */
??????????? pj_ioqueue_unregister(tp->key);
??????????? tp->key = NULL;
??????? } else {...
.. does the close asynchronously, at least on linux.
