About "Out of memory"

Hi!
My web app is a photo viewer, which gets 6 photos once from my web server and shows these photos in one page. The user can tap "next page" button on toolbar to fetch the next 6 photos. I use [I]mwl.insertHTML()[/I] to replace the old photo page with the new.
But after tap and tap "next page", about dozens of times, the app crashes with "out of memory" error. I think whether the html and photo images was not released when [I]mwl.insertHTML()[/I] called frequently? If so, how can I release the memory before [I]mwl.insertHTML()[/I] was called? Or, there are other problems?
Please give me any help.
BRD.

I had also face the same problem in my J2ME S40 app, have solved that problem by calling system.gc() method.

Hi,

Could you share some code? I would help to get started and to find possible fixes.

Yes, [I]system.gc()[/I] is effective in java, but how can I make the save effect in S40 web apps?

Hi isalento,
My code is bellow, this function handles the response of the http request called by the "next page" button.

function onPhotoList(xmlDoc){
var html = '<div class="tab_mag">';
html += '<table id="m_tab" cellspacing="2" border="0" style="border-collapse:collapse;" summary=""><tr>';
var recSets = xmlDoc.getElementsByTagName("rsp")[0];
for (var i = 0; i < recSets.childNodes.length; i++){
if (i > 0 && i % 3 == 0){
html += '</tr><tr><td style="height:5px" /></tr><tr>';
}
var rec = recSets.childNodes[i];
var obj = new Object();
for (var j = 0; j < rec.childNodes.length; j++){
if (rec.childNodes[j].hasChildNodes()){
obj[rec.childNodes[j].tagName] = rec.childNodes[j].firstChild.nodeValue;
}
};
html += '<td onclick="g_inSearch = false;getPhotoInfo(parseInt(' + obj["id"] + '))" valign="top">';
html += '<div><img src="http://12.34.56.78/images/';
html += obj["img"] + '" alt="' + obj["type"] + '" width="60" height="85" />';
html += '</div><div>' + obj["qishu"] + '</div></td>';
obj = null;
rec = null;
}
html += '</tr></table></div>';
mwl.insertHTML("#channel_list", html);
mwl.switchClass('#views', 'view0', 'view1');
recSets = null;
html = null;
}

Thanks for the code.

I couldn't instantly reproduce the problem with a hacked version of mine.
What device are you using for testing?
How big are images that you try to load?

Hi isalento,
Our test device is X3-02.
Every image size is 60x85pix, about 5KB.
The error always appears after 20-30 page turning.
I think the problem may be caused by xml parse, or mwl.insertHTML(), right?

Hi,

I discussed with RnD about this issue.
Could you check what Ovi Browser version you are using?
