Server Application Unavailable errors for ASP.NET application, recycle default application pool required
Posted on 2009-07-07
Running IIS 6.0. I have 100+ websites on the server, but only a few use any ASP.NET, but in the past few weeks something seems to be crashing. I get this error when trying to load a page that uses ASP.NET:
Server Application Unavailable
The web application you are attempting to access on this web server is currently unavailable. Please hit the "Refresh" button in your web browser to retry your request.
Administrator Note: An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Please review this log entry to discover what caused this error to occur.
I have no idea how to diagnose this. My solution has been to go into the application pools, and I have to select "recycle" on the default application pool, which is what they all use. That immediately fixes the problem, but it seems to be happening more and more often. I'm hoping someone can help me figure out what's going on. I don't program in ASP.NET myself, just have a few installed apps that use it. I will provide any other info, logs, etc., that might be needed. Thanks!
