Memory leak

Hello,

i have a problem with the grid in IE 6/7.

The grid has some circula references so the IE 6/7 is not able to release the memory until the page leaves to another domain.

You can see the memory leak if you use the Drip tool (http://www.outofhanwell.com/ieleak/index.php?title=Main_Page) and navigate with it to the expamle http://www.activewidgets.com/examples/2.5/basic.htm.

Hit the "Auto-Refresh Page" button an watch the memory usage grow in the bottom pane.

Any sugestions?

Have you tried same page locally?
I can imagine a few reasons because that particular online sample is wasting some memory.
mod rewrite ... php code ??
just guessing , needs to be comfirmed by Alex.
HTH

No did't try it locally. But don't think it would change anything. The html and java executed by the browser is just the same when it's requested by a webserver or from a local file.

The only thing that could differ is the securty-context (intranet / internet / local file) and the would make no changes to the memory usage.

Hello?
No sugestions???

I don't see any significant memory leaks on this page. If you keep refreshing the page the memory keeps going up and down, but the average does not increase over time. I am looking at IE7/XP - iexplore.exe process private bytes as shown by performance monitor (perfmon.msc).

The possible explanation why Drip reports memory leaks could be in this sentence (from Drip docs, https://ieleak.svn.sourceforge.net/svnroot/ieleak/trunk/drip/docs/index.html , 'Drip limitations' section) -

Drip does not intercept setting the outerHTML property of an element.

Most likely Drip attaches to the nodes which are later released via outerHTML and thus creates memory leaks by itself. The list of 'leaked nodes' shown in Drip contains the nodes which were destroyed via refresh() call, which is using outerHTML in IE.
