PHP - Random Session Failure

I have been posting on bugs.php.net about this and of course sniper gave the usual 'fixed in CVS', I was wondering if anyone here has experienced this.

Basically sessions are great. Everyone uses them and they are the standard for secure user information storage. However with PHP 4.x and above it seems that sessions are randomly failing. Everything will be fine 99% of the time, but 1% of the time the session will just die and log the user out.

I have heard this being attributed to several things, from two session ids being stored in the cookie to the cookie timing out prematurely.

I know quite a few people have experienced this... has anyone found a temp fix or a workaround? An actual fix would be great but at this point I just want to get this bug taken care of. Thanks.
