Description
On all browsers (Opera, IE, FF, Chrome) I have observed the memory leaks about 4 or 8kB on each ajax call. The php returns proper simple json text.
Working sample: http://macs.pl.tmm.pl/gold/player/ajaxtest.html
<!DOCTYPE html PUBLIC "-W3CDTD XHTML 1.0 StrictEN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> <head> <title>Test</title>
<script type="text/javascript" src="jquery_ui/js/jquery1.6.2.js"></script> </head> <body>
<script>
var s = function(){
};
var f = function(){
};
var t = function(){
$.ajax({
type: "POST", data: , async: true, url: "http://macs.pl.tmm.pl/gold/progress.php", dataType: "json", timeout: 10000, cache: false, success: s, error: f
});
};
setInterval(t,5000);
</script>
</body> </html>
Thank you for assistance.

Additionally, what tools or methods are you using to observe these "leaks". I just took 6 heap snapshots, one per request over 6 requests and the heaps are all the same

Replying to rwaldron: I have used the resource monitor (on Windows platform). I left the endless loop for 1 hour and comparing amount memory before and after. This is very strange for me, since nobody reported the same issue.

I am not seeing a leak with that test case. christophorus, can you verify that and perhaps try to change that test case so that it leaks?

Thank you for the test. I made following test: your case on Chrome(last), FF(6) and IE(9), and the result is that memory is (in my opinion) on Chrome and FF but not using IE.9. I made this test on Vista(32). Please make me advice how I can proceed now. BTW. my case doesn't leak on IE(9) as well.

Did you mean to attach a link to a test case?

Because we get so many tickets, we often need to return them to the initial reporter for more information. If that person does not reply within 14 days, the ticket will automatically be closed, and that has happened in this case. If you still are interested in pursuing this issue, feel free to add a comment with the requested information and we will be happy to reopen the ticket if it is still valid. Thanks!
Thanks for taking the time to contribute to the jQuery project! Please provide a complete reduced test case on jsFiddle to help us assess your ticket!
Additionally, be sure to test against the jQuery Edge version to ensure the issue still exists. To get you started, use this boilerplate: http://jsfiddle.net/FrKyN/ Open the link and click to "Fork" (in the top menu) to get started.
