Yes. The next snapshot will give you a way to get out of that situation (probably tomorrow). 1) There's a new "kill" command, "java -jar lib/resin.jar kill", which detaches the task from inside the watchdog and also kills the process (currently using the Process.destroy(). For Resin-Pro, it might be possible to add kill -9 at some point.) In your case, where you've killed the broken Resin instance with kill -9, the "kill" command will force the process detachment from the watchdog-manager, i.e. it will let you start a new instance even if the original "stop" thread gets stuck. 2) There's a new "status" command, "java -jar lib/resin.jar status" which will tell you the current state of the watchdog-manager and help debugging. 3) The watchdog instances are now registered with JMX. So you can use jconsole to hunt down the problem. 4) Most importantly, the watchdog has been refactored considerably. Specifically, the number of objects/fields changing on a start/stop has been reduced to essentially a single field/task. So there's much less opportunity for anything to go wrong. The docs will be in http://caucho.com/resin/doc/resin-watchdog.xtp. It's a bit sketchy at the moment, but several watchdog examples that should help people configuring it. -- Scott > > > S! > D. > > > _______________________________________________ > resin-interest mailing list > resin-interest@caucho.com > http://maillist.caucho.com/mailman/listinfo/resin-interest _______________________________________________ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
