Hi all,

Are there any known issues with 0.16.2 with regards to the Zen Discovery  
module? We have a node that refuses to join the cluster most of the time. I  
have created a gist with the debug logging here:

Can anyone help shed some light as to why it won't join? Is there some extra  
logging we can turn on to help us diagnose the issue?

Thanks,

Adam

Hey,

Are you relying on multicast discovery here (I assume you are, based on  
the logs)? Can you try and increase the ping timeout for the discovery  
process and see if it helps? You can set increase it by setting:  
discovery.zen.ping\_timeout to a higher value than the default 3s.
