An SRV query is actually sent (but only if there's an A record for the the given notification address), the higher priority address is chosen, but if this fails it never failover to a lower priority address. Also if notification server goes down, I haven't seen any attempt to re-contacting it in case it goes back on-line. Or may be I didn't wait enough time to observe it. I think it would be nice to have the information of notification servers in DNS SRV records. This would help in building a distributed infrastructure, rather than having such info in static configuration files, which are more suitable for clusters. > > > > > > > > > I will try to replicate your scenario and come back with a > solution > > > shortly. > > > > > > > > I have a patch which is working in my tests but I am waiting to hear > of any possible side effects. It should be in master branch shortly. I saw the patch on sr-dev. Thanks! - leonardo
