Dave,
We experienced a similar issue. Hazelcast attempts to add tickets from the
other servers but the timeouts differ. We use one config with 4 cas servers.
Opted to take the hit and brought all 4 down. Outage was only a few minutes.
I do like the idea of editing the hazelcast ips.

So I was just doing the same thing... hopefully you've already figured this out
but....
Hazelcast doesn't seem to like it when you change certain values while it's
running. So you can handle this two ways:
1. Bring down all servers using Hazelcast, make the changes and bring them back
up, or to keep things running a bit better in Prod,
2. This is assuming two CAS servers running Hazelcast and Hazelcast is
configured via hard-coded IPs... so you're mileage may vary
- edit Server1 cas.properties to make the change you want *and* remove the IP
addess of the other Hazelcast server. Restart tomcat
- edit Server2 cas.properties to make the change you want and restart. Note
that it will connect to the Server1 Hazelcast but you've already made the
change there
- edit Server1 cas.properties to add back the IP address of Server2 Hazelcast
and restart
That second method has worked for me. Anyone have a better way to deal with
this?

Hi all, I've had searched around here for a similar problem but couldn't find
it so I am posting in hope somebody can help me find and answer, or show me
where I am doing things wrong.
I need to modify some cas ticket registry, expiration policy, configurations, I
want to change the Time To Kill of ST tickets, but when I use the Configuration
written on the DOC:
cas.ticket.st.time-to-kill-in-seconds=60
I can't get to start CAS, and I find an error of Hazelcast. I use Hazelcast for
ticket share on my cluster environment, so I guess that I can't use default
ticket configuration properties when I use hazelcast because it would be
delegated to it.
The problem is that I can't find the equivalent configuration to use for my
hazelcast configuration (if there is one...). Do somebody knows about the
correct property? Is there something I can do to get my desired result?
Thanks for your time.
The error I get on catalina.out:
