Finally I found out how to configure Jboss cache. If someone has the same proble here it is: <!-- Specifies the time in milliseconds for elements from the replication queue to be replicated. --> 10000 <!-- Specifies whether or not to use a replication queue (true/false). This attribute applies to synchronous replication mode only (i.e., CacheMode attribute is REPL_ASYNC). --> true <!-- Specifies the maximum number of elements in the replication queue until replication kicks in. --> 100 View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4227826#...
