Javascript memory leak in Internet Explorer

I developed a website 开发者_如何学运维that is using jquery ajax. Every minute an ajax request send to get json data. This json data is then parsed and inserted into the DOM.

In Chrome and Firefox this works just fine, but in Internet Explorer I have a huge memory leak (after an hour or so the IE process takes up to a few hundred MB's).

How do I start debugging this? How can I see which functions/variables use all this memory?

This is solved. It was caused by an outdated jquery version.
