() Previous frame inner to this frame (corrupt stack?) (kgdb) the 'current process' (kdeinit in the above crash) changes, but is always one of the KDE parts; of course the problem is not KDE related, it is just that the system comes under heavy usage in that moment; I already run 'memtest 128' for some hours without any noted problem in memory; test are just passing fine; the same problem is with 7.0-RELEASE as with RELENG_7; what can I do to nail this down? it sucks somehow seeing it crashing on startup in the morning in the office :-(( thx matthias -- Matthias Apitz Manager Technical Support - OCLC GmbH Gruenwalder Weg 28g - 82041 Oberhaching - Germany t +49-89-61308 351 - f +49-89-61308 399 - m +49-170-4527211 e - w http://www.oclc.org/ http://www.UnixArea.de/ b http://gurucubano.blogspot.com/ A computer is like an air conditioner, it stops working when you open Windows Una computadora es como aire acondicionado, deja de funcionar si abres Windows
