Hi,
I have similar problem with glassfish clustering.
sessions from my app, not replicated to another node, but in all other
aspects cluster works correctly.
*asadmin list-instances -l*
NAME HOST PORT PID
CLUSTER STATE
portal-instance1 localhost 24848 6343 portal-cluster
running
portal-instance3 fss-portal3 24848 4628 portal-cluster running
Command list-instances executed successfully.
*asadmin get-health portal-cluster*
portal-instance1 started since Wed Jun 22 17:17:20 MSD 2011
portal-instance3 started since Wed Jun 22 17:17:21 MSD 2011
Command get-health executed successfully.
When i'm running asadmin validate-multicast --multicastaddress 224.0.0.251
--multicastport 24567 --bindaddress 172.17.12.172 --timeout 45 on second node
in logs appears these error:
[#|2011-06-22T17:35:16.680+0400|WARNING|glassfish3.1|ShoalLogger|_ThreadID=29;_ThreadName=Thread-1;|GMS1071:
