IE Memory Leak when using telerik controls.
We see that there is Memory Leak when using Rad controls.  IE process memory keeps increasing until the process crashes.  I am attaching a sample webpage default.aspx.  You could use it to simulate it.  Leave the IE browsing running after navigating to the page.  You gradually see that the memory consumed by IE increase.  Please also note I have not written any javascript used default functionality provided as is.
These application where in we use telerik run for long and ajax calls keep running in the background and hence they are crashing.  Please do have a look and if possible let us know if there is any way to avoid it.
version of telerik that we have tried: 2012.3.1308.40 & 2013.1.220.0
version of IE used 8.0.760.1.17514
other versions of IE also have the issue.  
Hope you respond soon.

I was able to replicate the memory increasing by commenting all of the Telerik RadControls on the provided code pages. Still the timer keeps increasing the page size on each 2000ms as it is enabled.

By analyzing the bytes sent/received using Fiddler2 it is seen that the post request goes into a loop which leads to page size increase - see attached screenshot.
