Based on what parameters we can conclude that a process is in hung state. ( 100% CPU Usage?? Or if any thread is continiuosly in wait state for a long time??? or ???? ) Can we conclude the given process is in hung state or not based on any process or thread properties (% CPU usage etc). How taskmanger is getting state of hung process? (Generally task manager displays "Not responding" if any process is hang.) Regards, Koti
