SYMPTOMS
When you are running a Microsoft ASP.NET application, the application may quit unexpectedly (crash) if the processor load increases to 100 percent.



CAUSE
This problem occurs when a computer that is running ASP.NET experiences an increased load on the processor. If the processor load reaches 100 percent capacity, the ASP.NET application worker process (Aspnet_wp.exe) may restart repeatedly until the processor load decreases.
