Hi All -
We have a deadlock problem with an app. Typically in such situations I follow Andrew Lindesay's excellent tutorial on using JDB to grab a thread dump off a hung instance and start digging from there. However, with this particular deadlock JDB doesn't work - i type "jdb -attach 8121" and then .... nothing. It just sits there. If i then kill off the instance in another terminal the jdb terminal springs into life saying the JVM has vanished.

I've checked I can connect to it and get a thread dump when the app is running happily so it must be the deadlock that is causing the problem.

Any ideas what is going wrong with JDB ? Or any advice on another way of tracking down the deadlock ?

This is how I get thread dumps: http://www.global-village.net/gvc.webobjects/ faq&mode=single&recordID=41413
