I am troubleshooting an issue where our web application will spike to 95-100% CPU and hang there until it is recycled or the server is restarted. I've been able to get some dumps using ADPlus when this is happening. (-hang option, no other special switches.)
That said, I'm noticing something else that is rather odd... whenever we do the ADPlus memory dump, IIS seems to create a new process for that application pool, and the old process just sits there 'orphaned', not doing anything?
Pretty much my only question at this point is: Is this normal?
