IIS crashed with the following error: ISAPI 'C:\WINDOWS\microsoft.net\Framework\v2.0.50727\aspnet_isapi.dll' reported itself as unhealthy for the following reason: 'Deadlock detected'. Any ideas what to look for causing this would be greatly appreciated. Thanks!

Reply Contact You can configure the application pool to orphan the worker process rather than kill it when this condition happens - you can then use adplus to collect a hang dump of the worker process which can be analyzed to figure out what in the process is deadlocked.

Reply Contact Is there any document that describes what ASP.NET means by " reported itself as unhealthy for the following reason: 'Deadlock detected'"? I would like to know how it decides if it's dead locked or not?   thanks   Pawel

Reply Contact It means that the asp.net thrads have not returned from whatever activity they were doing for a very long time and asp.net has run out of threads - this would normally indicate deadlock. This kb also talks about how to generate dumps for analysis for this condition. Anil Ruia Senior Software Design Engineer IIS Core Server

I've tried before  the article you mentioned but IIS recycled the process and didn't create any dump. I suppose my only option is to run adplus in crash mode even though it affects performance. Do you have any other ideas where to look to find more information?
