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 22 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 a 500 status code, it means there is something wrong on the website.

Human error is usually a programming mistake or configuration error. Usually this happens if someone makes a quick fix on the server, without testing it first on a test internal server environment or when a file that isn't supposed to is deployed to your production environment. These are things that should never happen, but still they do and you want to know about it immediately.Common errors: Typing errors in .htaccess files Syntax errors in PHP / Python / Ruby / Perl code Wrong configuration file (e.g. a development one) Unhandled edge cases, e.g. when there is no matching record in the database The other main cause for HTTP internal server error 500 response or Internal Server Errors is an error on a service you depend on.

There are a number of causes for a 500 Internal Server Error to display in a web browser. Below is a sample error message. This article provides information on the most common causes. Check the Error Logs! With any error message, particularly one as broad as the 500 Internal Server Error, you will first want to check any Apache and PHP error logs for your server. These logs can provide valuable context related to any code failures or other potential causes of a site failure. For information on where to find the logs for your server, please see: Where are the access_log and error_log for my server? Error with an .htaccess file If you are using a .htaccess on your site, it may be interfering with the web page you are trying to load into your browser. Please double check the .htaccess configuration. Any syntax errors will cause a 500 Internal Server Error message to be displayed instead of your website. To confirm whether a misconfiguration .htaccess is the cause of the 500 Internal Server error, either remove or rename the .htaccess file temporarily and then try to reload the page. See also: Using .htaccess rewrite rules Using .htaccess files PHP Coding Timing Out If your PHP script makes external network connections, the connections may time out. If too many connections are attempted and time out, this will cause a "500 Internal Server Error." To prevent these time outs and errors, you'll want to make sure that PHP scripts be coded with some timeout rules. Typically, however, catching a timeout error when connecting to a database or externally to remote resources (example: RSS feeds) are difficult. They, in effect, freeze the script from continuing to run. Removing any external connections can increase both the performance of your website and decrease the chances of you receiving a "500 Internal Server Error.
