Using PHP on a commonly used server (provider) with session files from other users stored there, let PHP craches with the probability of session.gc_probability. (I've no read/write access of the session files of other users.) PHP is configured using: --with-mysql=/usr/local --with-config-file-path=/usr/home/as/php --enable-debug=no --enable-track-vars=yes --enable-force-cgi-redirect=yes --enable-trans-sid=yes --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=8011
