Hazelcast ticket registry in CAS 4.1.9, connection refused error when startup

[Yan Zhou]

Hi,

I am using Hazelcast as the ticket registry for my CAS 4.1.9 overlay.  On my local instance of CAS, in the cas.properties, I specified this:

hz.cluster.members=localhost

When starting up CAS, it works fine, but I see these error messages, It fails to connect on ports 5702, 5703, etc.  But, I can telnet to these ports just fine.

What is the nature of these errors?

Thanks!

Yan

Just an info message telling that HZ cannot connect to other members of a cluster as there are no other members (by default it auto forms the cluster on ports 5701… and auto increments it for members joining the cluster). So, in short, nothing to worry about here.

Cheers,

D.
