In Drupal 4.7 there was a similar problem, when upgrading to php 5.2.
The following line in settings.php solved it:
|register_shutdown_function('session_write_close'); |||
maybe it will help you too.

Searched Drupal.org and couldn't find a definitive answer. Is Drupal 5.x not compatible with IE 7? We keep getting logged out and access denied errors when viewing our site with IE7. Doesn't happen with Firefox.
The odd thing is that it happens frequently, and from what I can tell seems to happen after viewing a node and trying to navigate elsewhere. The result is the login menu and access denied.
settings.php seems to be set up correctly, with a base path defined. We also upgraded to 5.2 to see if that would resolve the issue (and set the $cookie_domain) but still no luck.
The only thing I can think of is that we're using the securepages module to use https for /user/* but I'm not sure if that would affect session/cookie.
Many thanks in advance. Brian
