Remove Telerik Cache and Release Memory

Question

The scenario: I'm using Telerik Report Viewer in my web application to show large reports (about 5000 records from my DB, resulting in a 80 page document to display). Everything was working just fine... but on this terrible day my app starts to throw a "Out of Memory" exception.

I realize that Telerik Report was caching all data and only releasing it after a long time(15 minutes or more). The cache for one report consume at least 300mb!

The things is... I want to empty this cached data AND release my memory. The memory consumpion persist even after I clear the cache using the following code:

HttpRuntime.Close()

//or

foreach (DictionaryEntry item in HttpContext.Current.Cache) {   
HttpContext.Current.Cache.Remove((string)item.Key);
}

Any ideias? Thanks in advance.

The quick and dirty way I found to prevent this issue is to export the report (pdf, rtf...) and not display it on the page.
