My test instance of jBPM wrote 21GB of logs in 5 days (mainly the timer servlet). We should have a look at changing much of the logging from debug level to trace level. One of the important guidelines for choosing between debug and trace is whether the log messages scale with the application usage. In the case of the timer servlet, they do, so the log level for timer messages should be trace. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4056543#...
