+6155.  [bug]           Treat ISC_R_INVALIDPROTO as a networking error
+                       in the dispatch code to avoid retrying with the
+                       same server. [GL #4005]<

 6154.  [func]          Add spinlock implementation.  The spinlock is much
                        smaller (8 bytes) than pthread_mutex (40 bytes), so
                        it can be easily embedded into objects for more

-
 - When the same ``notify-source`` address and port number was configured for
   multiple destinations and zones, an unresponsive server could tie up the
   socket until it timed out; in the meantime, NOTIFY messages for other servers
   silently failed.``named`` will now retry these failing messages over TCP.
   NOTIFY failures are now logged at level INFO. :gl:`#4001` :gl:`#4002`
 
+- When ISC_R_INVALIDPROTO (ENOPROTOOPT, EPROTONOSUPPORT) is returned from
+  libuv, treat it as a network failure, mark the server as broken and don't
+  try again. :gl:`#4005`
