note 89572 rejected from ref.session by danbrown

Note Submitter: stefan at braeu dot co dot at ---- I'm fighting with a very strange session problem - maybe someone experienced somthing similar: at random times (sometimes after a few minutes, sometimes after a couple of hours) _all_ active sessions get cleared - the session-cookie is still active, and the session-file in /tmp still exists (but with a filesize of 0 bytes). this affects all sessions (regardless which php-program started it). i wrote a testscript, that does nothing but starting and reading a session-variable. this also gets cleared. my big question is: is it possible to accidentally kill sessions of other client-users from other programs in PHP? (the different scripts all run as the same server-user 'www'). i'd be grateful for any glue. thanks.
