i did a little debugging and am finding that in org.jboss.seam.core.Manager.restoreAndLockConversation() the call to ConversationEntry.lock() is returning false because Manager.instance().getConcurrentRequestTimeout() (which is set to 1000 ms) has been exceeded. it looks like our request processing is taking more than 1000ms to complete, so i guess i need to increase the value of org.jboss.seam.core.manager.concurrentRequestTimeout?
