Thanks. Some more questions: -- In a scenario with two nodes, if I shutdown one, the other is instantly ready to receive and respond to requests, or it is necessary to wait a while? In a procuction scenario we cannot wait, because requests are frequently. -- The 35 seconds refers to the initial time? -- Is there any recommended configuration (basically If one tomcat crashes I want that the other responds immediatly to the requests)?
