Lets try this:

Edit your includes/class_core.php file and find:

		if ($proxy)
		{
			define('ALT_IP', $this->ipaddress);
			define('IPADDRESS', $this->alt_ip);
		}
		else
		{
			define('IPADDRESS', $this->ipaddress);
			define('ALT_IP', $this->alt_ip);
		}

		define('SESSION_HOST',   substr(IPADDRESS, 0, 15));
	}

And change it to this:

		if ($proxy)
		{
			define('ALT_IP', $this->ipaddress);
                        define('IPADDRESS', $_SERVER['HTTP_X_FORWARDED_FOR']);
		}
		else
		{
			define('IPADDRESS', $this->ipaddress);
                        define('IPADDRESS', $_SERVER['HTTP_X_FORWARDED_FOR']);
		}

		define('SESSION_HOST',   substr(IPADDRESS, 0, 15));
	}

It may work, I can not say for sure as I am not getting that issue on my sites.
