Hazelcast configuration on CAS 4.1.9 overlay

[Yan Zhou]

Hi,

CAS 4.1.9 overlay with Hazelcast as ticket registry.  Two instances of CAS running on each server. With two servers, four instances of CAS, and request round robin to the four CAS servers.

in cas.properties on each CAS instance:

hz.cluster.members=server1.com,server2.com

First of all, is that a proper configuration (everything else on Hazelcast is default value)?

In cas log, I see this.  What does this mean, why does the members go down from 4 to 3 and to 2?  And, it seems that members on 5702 are being dropped. 

Thanks,

Yan
