Hello,

a solution for the moment would be to add a new flag to mark the destination for no-keepalive, so it is considered to be active always.

Right now the issue is created by the fact that keepalive is enabled and the implementation needs the IP at start up.

However, for NAPTR/SRV records, there can be a different IP returned for each query, so it might not bring much benefits to do keepalives in such cases. This can be added if someone wants to develop it.

Then, just to refresh, you can do SRV based load balancing without dispatcher, it is done by tm and core automatically.

Cheers,
Daniel

The reason I posted here first was that I wanted to rule out any obvious thing I was missing here since there already was a thread open on it. 

Cheers,

Pat

Hi Patrick,

the best would be probably to file a issue about this behavior on our GitHub
tracker. Then it could be analyzed in more details.

Best regards,

Henning
