SYMPTOMS
The system becomes low on memory resources when Web pages that contain script continuously appear.

The memory leak is small. However, eventually the memory leak can interfere with KIOSK-type devices that continuously cycle through HTML pages. After several hours of operation, memory resources are exhausted, and the device slows down. You may receive the System Out-of-Memory (OOMUI) dialog box if your operating system implements this dialog box.



CAUSE
The memory leak is caused when Urlmon.dll saves a URL for an embedded binding to the global garbage collection pool. The global garbage collection pool is only cleaned up when you exit the application.
