Application: w3wp.exe Framework Version: v4.0.30319 Description: The process was terminated due to stack overflow. the stackoverflow issue is occurring on one of the production system, it clears when we start the app pool configured to this application, and when we see the event logs it says "The process was terminated due to stack overflow" how can i find out what is the root cause for this issue and how can i drill down to figure this out on production system.? Note : it seems to be not occurring at development or production system
