RE: Dead threads
Howdy, If a thread is dead it will have been GCed. Use a thread dump (kill -s QUIT processId) to get the current list of threads and what they're doing on stdout. There are also programmatic ways to go about this: I've posted at least three times in the past the complete code for a thread-crawler type of class that will display all the threads in the JVM, what they're doing, their state, etc: you can search the list archives for it.

I got this code by searching one list (I think it is tomcat-dev). code is given below. // to print the number of threads in tomcat. ThreadGroup systemthreadgroup; ThreadGroup parentthreadgroup; systemthreadgroup = Thread.currentThread().getThreadGroup(); while ((parentthreadgroup = systemthreadgroup.getParent()) != null) systemthreadgroup = parentthreadgroup; out.println(Thread.currentThread().getName() + : activeCount = + systemthreadgroup.activeCount()+BR); Thread[] array = new Thread[systemthreadgroup.activeCount()]; int count = systemthreadgroup.enumerate(array); for(int i=0;icount;i++) out.println(Thread.currentThread().getName() + :array[+i+] = + array[i].toString()+BR); hope this helps.
