/* For UDP there is one server instance consisting of udpserverrd and udpserverth
* rd is responsible for init and launching wr
* For TLS there is a server instance that launches tlsserverrd for each TLS peer
*/
/* Bugs:
- * TCP accounting not yet supported
- * We are not removing client requests from dynamic servers, see removeclientrqs()
- * Need to remove UDP clients when no activity for a while...
+ * May segfault when dtls connections go down? More testing needed
* Remove expired stuff from clients request list?
+ * Multiple outgoing connections if not enough IDs? (multiple servers per conf?)
+ * Useful for TCP accounting? Now we require separate server config for alt port
