Repeater destroy repeated items

I am stuck in improving the performance of repeater. I have repeater(recycleChildren = "true")开发者_运维知识库 with a custom repeating component in a pop up window.

The problem is when I close the popup window it does not destroys the instances of repeater item. When I repeater the popup window profiler show the instances count as: reptur.dataProvider.lenght + the instances that were there at the time of closing the popup window.

So the memory shoots up & not release as I close & open the window.

Please help me out in releasing the repeater instances on cosing the window.

Thanks in advance.

try System.gc()
or set them to null manually
