@sibro,

The patch has undergone some evolution since Hershel first posted. You'll find the changes in the initialize() function.

@krypto et al,

I've cracked a problem like this. See http://forum.civicrm.org/index.php/topic,31800.msg136241.html#msg136241

There's an easy test to see if your issue is the same as mine. Look at the Drupal sessions table for multiple rows sharing the same ssid.

select a.* from sessions a, sessions b where a.ssid = b.ssid and a.timestamp < b.timestamp
That query should return no rows, but if it does you're having the same issue as I did. There's a patch in that post to fix the issue.

Using drupal 7.26 Civicrm 4.4.4

I still have this issue with both undefined variable being
I get this error in my log files everytime a anonymous person visits any website page including drupal pages:
Notice: Undefined variable: _SESSION in CRM_Core_Session->__construct() (line 86...sites/all/modules/civicrm/CRM/Core/Session.php).

and the notice that a session has already been started
Notice: A session had already been started - ignoring session_start() in CRM_Core_Session->__construct() (line 87 ...sites/all/modules/civicrm/CRM/Core/Session.php).

I checked my session.php file to see if the code was updates and it does contain the patch as metioned below:
  function __construct()
     {
 if (!$_SESSION) {
 session_start();
 }
         $this->_session =& $_SESSION;
     }

Any help would be greatly appreciated.

Thank you Ken for helping with this issue.
The notice in Drupal log is this:
Notice: Undefined variable: _SESSION in CRM_Core_Session->__construct() (line 86 of .../modules/civicrm/CRM/Core/Session.php).
Severity   notice

AND

Notice: A session had already been started - ignoring session_start() in CRM_Core_Session->__construct() (line 87 of .../modules/civicrm/CRM/Core/Session.php).

In my session.php file in CiviCRM from line 84 to 90:
  function __construct()
     {
 if (!$_SESSION) {
 session_start();
 }
         $this->_session =& $_SESSION;
     }
Thank you for you help on this.

@avanoers,

You seem to have a mutilated CRM/Core/Sessions.php

This is the __construct() function from 4.4.4 which I just downloaded.

  function __construct() {
    $this->_session = null;
  }

You seem to have applied an old patch from @hershel and a lot of water has gone under the bridge since then. Try restoring the original 4.4.4 code. The patch I supplied fixes a different issue to the one you're reporting.
