aspnet_wp process accumulates memory usage up to the point when it's more\nthan 60% of available RAM (2G) and none of .NET applications function.\nSometimes user is able to login, navigate between the pages but can't perform\nany operations that generate thing like PDF files using Crystal Reports etc.\nSometimes the application can't even be loaded and sign-in page stays blank.\nThere are no events that are logged in the event viewer to point to this\nproblem. However we do find these errors occasionally:\n\n"aspnet_wp.exe (PID: 3900) was recycled because it was suspected to be in a\ndeadlocked state. It did not send any responses for pending requests in the\nlast 180 seconds. This timeout may be adjusted using the <processModel\nresponseDeadlockInterval> setting in machine.config. "\n\nand\n\n"aspnet_wp.exe (PID: 3328) was recycled because it failed to respond to\nping message. "\n\nand\n\n"Failed to execute request because QueryInterface for ASP.NET runtime\nfailed. Error: 0x80004005 Unspecified error "\n\nCan you tell me how we can trap or log this information so that we can find\nwhat is causing the leak and solve it.
