I think that is very useful and I have applied your patch to the current trunk. One thing I changed is that the signal handler is only installed if the threadframe module is installed (otherwise, you'll get the default behavior). I also made this work on Windows by using SIGBREAK here. So on Windows, you can shutdown/restart with Ctrl-C and you can now get a thread dump with Ctrl-Break. However, I have one problem under Windows: Hitting Ctrl-Break does only work one time. For some reason, Windows ignores subsequent Ctrl-Breaks. Does anybody have an explanation for that behavior? -- Christoph ------------------------------------------------------------------------- Using Tomcat but need to do more?
