  This is a dupe of bugs #17846, #19029, #19972.  I wanted to update the version and circumstances.  For the most part everything works fine, then randomly the session will fail.  In my php.ini the max_gc_lifetime (don't know exact spelling) is set to 0 (on browser close).  Everything else is set to the standard settings.

  This is an annoying bug because it's hard to isolate it.  
I have heard some theories of the cookie prematurely expiring, two sessionid's in the cookie, etc.  I tried the latest CVS this morning on my test server and the error is still present.

  It is not a problem with my code, all I have is a session_start() and $_SESSION["username"] at the top of every page to check if the session exists.  I do not have any custom session handler and pretty much have a standard install for Win32 (AF doesn't let us use Linux).

  Any ideas??

Where does it say that setting session.gc_maxlifetime to 0 would give should behaviour? It's just what is says _maximum_  
lifetime of session, 0 means it's always cleaned whenever
the random cleaning happens.

Expected behaviour -> not bug.

Correction, max_gc_lifetime was supposed to be cookie_lifetime (sorry).  Setting the cookie lifetime to 0 (according to the website) will keep the session active until the browser is closed.

  That does not change the nature of the bug.  Please read my post.  The bug is that the session is randomly ending.  It is the stock php.ini except for the cookie lifetime.  Everything is standard.  This bug has been brought up several times and the response has been 'fixed in CVS' but it has not been.  I realize the session functions have been rewritten but please at least acknowledge the problem.

I use sessions lot myself, if there really was some bug
in it, I'd be first to know, really.

I think you just don't understand how the garbage cleanup
works..setting the "session.cookie_lifetime" only affects
the cookie lifetime. Still the _random_ garbage collecting hits in when the lifetime of a _session_ exceeds the max lifetime, regardless of what the cookie lifetime is.
