I am trying to run the carts example (*/examples/jsp/sessions/carts.jsp*)
with two nodes, on ports 8090 and 8190. The nodes are working fine
individually. However, I am trying to create a cluster with static members
(without multicast), but I keep encountering the following error -
09-Jun-2023 22:17:21.193 SEVERE

message through cluster sender.

I am trying to do this to achieve non-sticky sessions. Please help me
identify the problem in my *server.xml*. I am using *tomcat 8.5* with the
default configuration, with the cluster settings added inside the <Engine>
tag. The *web.xml* for both tomcats already contains the <distributable/>
tag.
