SYMPTOMS
Unhandled exceptions in a Microsoft ASP.NET application may cause a deadlock and may cause the ASP.NET process to recycle.

ASP.NET has health monitoring, and this health monitoring may cause the Aspnet_wp.exe process to be recycled. An example of this behavior occurs when ASP.NET determines that a deadlock state exists. When a deadlock state exists, an event that is similar to the following is written to the application event log: Event Type:    Error Event Source:  ASP.NET 1.1.4322.0 Event Category: None Event ID:      1003 Date:          7/24/2004 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.



CAUSE
This behavior may occur if an exception that causes process recycling is not processed completely.
