I have a web application run in IIS 8.5. For unknown reasons sometimes w3wp process takes 100% processor usage finaly causing restart. I've tried to use debug diag tool v2 but I have a problem setting up the monitor/trigger because when I get to pick the process to create perfomrance counter for I get a bunch of processes in dropdown that are simply numbered (w3wp, w3wp#1, w3wp#2...) and I don't know which one represents which iis process (I have many iis apps) because in this window I can't see the PID's. Another thing is I've set some triggers in debugDiag for a ragne of processes and I've got some dumps created, but I've noticed a lot of new w3wp processes were created with status "suspended" which I can't kill (maybe to low privilege?). I suppose theese were created by DebuDiag because number of new processes equals number of created dumps.
Can anyone tell me what I'm doing wrong here and how to do this right? Thanks.
