In my experience, if the event log is empty than the request wasn't correctly routed to the worker process. In one of our recent deployments we saw the app work intermittently with about 50% of the requests randomly failing with the 500 error and nothing in the logs. I suspect something is going wrong with the AppDomain unload that occurs after deployment. Out of curiosity, are you running antivirus in your production environment? Does an IIS reset solve the issue (until the next deployment)? –ShadowChaser Feb 21 '13 at 16:17 add a comment| 4 Answers 4 active oldest votes up vote 23 down vote accepted Take a look at IIS7's Failed Request Tracing feature: Troubleshooting Failed Requests Using Tracing in IIS 7 Troubleshoot with Failed Request Tracing The other thing I would do is tweak your
IIS 500 errors leave clues in the log Email ThisBlogThis!Share to TwitterShare to FacebookShare to Pinterest Yesterday I was playing around with thevalidateIntegratedModeConfiguration="true" setting on http://www.dotnetnoob.com/2012/03/iis-500-errors-leave-clues-in-log.html IIS 7.5. To my surprise I got an empty response back, with no indication of what went wrong. Looking at the response with Fiddler yields: HTTP/1.1 500 Internal Server Error Server: Microsoft-IIS/7.5 X-Powered-By: ASP.NET Date: Mon, 05 Mar 2012 15:59:52 GMT Content-Length: 0 There's not much to work with here! I checked the event log, there was nothing there. So I started internal server looking around for an error log of some sort (I used to play with Apache back in the days) turns out there's no such thing in IIS. Some googling led me to an in-depth article:Troubleshoot IIS7 errors like a pro. I enabled detailed error messages for my website, still no luck. Finally, I figured out that the easiest way to get an indication internal server error of what's going on is to check the IIS log. In the default setup, IIS keeps the logs for each website in:C:\inetpub\logs\LogFiles. Here's a log entry from my logfile (shortened for readability): 2012-03-05 15:59:52 ::1 GET /Somesite/ - 443 - ::1 Mozilla/5.0 500 22 50 1 Notice the "500 22" in the log? That's the 500 error, along with its substatus. The substatus is the key here, as you can look that up inMicrosoft's document onThe HTTP status codes in IIS 7.0 and in IIS 7.5. Voila, my error was actually: 500.22 - An ASP.NET httpModules configuration does not apply in Managed Pipeline mode. I can work with that. Of course, you could also enable failed request tracing in IIS if you're a pro, here's a walkthrough by the IIS team:Troubleshooting Failed Requests Using Tracing in IIS 7. I tried it, and it also revealed the substatus of the response. Still, checking the IIS log was a much faster way of getting an indication of what the problem was, and sometimes that's all you need. So check your logs first, then start troubleshooting like
