Cold Fusion 9 Server - 500 Server Error

[OanhT]

Hello.  We recently installed the CF 9 Enterprise Edition  - 30 Day Trial version. It is running on Windows 2008.

Everthing works fine with one exception.  If we wait an extend period of time between accessing a web page on the server we receive a 500 Server error.  If we click on the browser Refresh button, once, sometimes twice,  the page  will load successfully.  From that point on we do not have a problem unless an extended period goes by without accessing  a web page.

Any help would be appreciated.

500 Server Error is often a generic error that could really be something easy to fix in your code.

Have you configured the Enable Robust Exception handling in the Debug Output Settings section of the ColdFusion Administrator?

Enable Robust Exception Information
Allow visitors to see the following information in the exceptions page:

IIRC If you do not have this enableds ALL errors generated by your code is a 500 Server Error.

If you haven't or you don't want to enable robust expception (which one should not do on a production system. You want the hackers to get as liitte information as possible) The errors are probably stored in the ColdFusion logs, unless you have disabled this for some reason.

To add to Skinner's advice.

1. Check the log files  that ColdFusion generates for the source of your errors.

2.  Check the Windows event log to see if anything is logged there.

I should append to my original post the fact that Server 500 error also occurs when attempting to open the ColdFusion Server administration page

after extended periods of Server inactivity.

I, too, am having the exact same problem descirbed here.

ColdFusion 9 64-bit

IIS 7

Windows 2008 Server 64-bit

After successfully installing Coldfusion9, I let the admin console sit idle for about an hour or so and when returned got 500 errors.  Restarting IIS and/or Coldfusion does not resolve it.  I cannot access the CF admin console because of the 500 error.  No indication of cause in any log.  Cannot set verbose setting as described in this forum because I don't have an admin console.  Need help.
