It seems that one JBoss node not join ths cluster as you can see only one ip address by the "CurrentView" field.Does both of the two JBoss instances use the same ip address with different ports?If so,you can see the folowing in the "CurrentView" field: i.e. [10.1.1.31:1099, 10.1.1.31:1299] You can check this. And if you use apache and mod_jk for loadbalance,then you can monitor it with jkstatus page. Hope this will help you.
