Providing a thread dump is the responsibility of the JVM, not JBossAS. A JVM thread dump always goes to the stdout. You could always redirect stdout to a file when launching JBossAS. Other alternatives: * Use JConsole of VisualVM - they both let you take thread dumps and I believe you can save them to a file * Use the listThreadDump operation of the jboss.system:type=ServerInfo Mbean. If you did this using twiddle you could redirect the results to a file. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4171386#...
