SYMPTOMS
During a time of inactivity, the following entry may appear in the Application Event log:

Event Type: Error

Event Source: ASP.NET 1.0.3705.0

Event Category: None

Event ID: 1003

Date: 4/24/2002

Time: 6:18:23 PM

User: N/A

Computer:

Description:

aspnet_wp.exe (PID: ) was recycled because it was suspected to be in a deadlocked state. It did not send any responses for pending requests in the last 180 seconds.

-or-

You may note that memory consumption has increased in the Inetinfo.exe process.



CAUSE
The deadlock condition and the increased memory consumption occur because ASP.NET does not remove requests from its internal request table. This occurs because a client has disconnected from the request. The following are a few common actions that might cause a client request to become disconnected:
 * A user closes the browser during a request.
 * A user clicks Stop during a request.
 * A user clicks a link before the page loads completely.

NOTE: This problem occurs when ASP.NET runs under Secure Sockets Layer (SSL). Some ISAPI Filters can cause this problem, also. This problem occurs more frequently on sites that have users who have slow connections.



RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next .NET Framework service pack that contains this fix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:
