APC Upload Problem

[vladapopster]

Imam problem vezan za progres bar pri ajax uploadu fajlova.
Na test serveru sve radi kako treba, dok isti kod prebacen na live server ne radi, tacnije vraca false.

HTML

<form target="hiddenframe" enctype="multipart/form-data" name="form1" id="uploadform" style="margin-left:6px;" action="" method="POST">
				<input type="hidden" name="APC_UPLOAD_PROGRESS" id="progress_key" value="{$upl_id}" />
				<input type="file" id="numlist" size="25" name="filefieldname" {literal}onchange="fandl_simple_sms(this.id,Array('numbers','choiceG','numlist'));"{/literal}/>
			    </form>
			    <input type="hidden" id="filename" value=""/>
			    <iframe name="hiddenframe" style="display:none" >Loading...</iframe>

Javascript

var params = { upl_id: upl_id	};
		new Ajax.Request(
			'/cust/klase/upload_progress.php',
			{
				'parameters': 	params,
				onSuccess: function(transport)
				{
					var resp = transport.responseText; 
					var odgovor;
					eval('odgovor = ' + resp);
					
					if(odgovor.status == "OK")
					{   
						$('uploadedfile').update("Uploaded "+odgovor.trenutno+"kb from "+odgovor.total+"kb");
						
						if(odgovor.procenat!=100)
							setTimeout("waitUpload('"+upl_id+"')",300);
					}
					else if (odgovor.status == 'LARGE')
					{
						$('uploadedfile').update(odgovor.message);
						return;
					}
				}
			}
		);

PHP skripta koja obradjuje velicinu obradjenog dela fajla

if(isset($_REQUEST['upl_id']))
{
    $status = apc_fetch('upload_'.$_REQUEST['upl_id']);
    if($status['total']>10000000)
    {
        echo json_encode(Array('status' => 'LARGE','message' => 'File is larger then 10 MB'));
        return;
    }
    $procenat=round($status['current']/$status['total']*100); 

    echo json_encode(Array('status' => 'OK','procenat' => $procenat, 'total'   => round($status['total']/1000), 'trenutno' => round($status['current']/1000)));
}

E sad problem je sto to sve na development serveru radi kako treba, dok na live serveru apc_fetch vraca false ili nista.
Da li je neko imao ranije neko iskustvo sa APC kesiranjem i progres barom za upload fajlova.

Hvala unapred.
