I don't have physical access to the system and have no way to tell if it turned it self off or just hangs. All I can tell is that it suddenly stops responding on the network and on the serial console, which makes manually entering ddb impossible. If the system is running the serial console is working as expected: I can enter ddb with ~ ^b, sysctl debug.kdb.enter=3D1 (or by typing kldload /dev/mem instead of mount_procfs ...). Another sio related thing where I'm not sure if it means anything: according to top -S, "swi4: clock sio" hardly ever leaves the state *Giant. top's output is logged every five minute and at the moment I have: [fk@tor ~]$ sudo grep "clock sio" /var/log/stats.log.bak | wc -l 1022 [fk@tor ~]$ sudo grep "clock sio" /var/log/stats.log.bak | grep Giant | wc = -l 1006 [fk@tor ~]$ sudo grep "clock sio" /var/log/stats.log.bak | grep WAIT | wc -l 16 Fabian --=20 http://www.fabiankeil.de/ --Sig_PI/0QyBgQocsOlDfIy9bt8H Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.4 (FreeBSD) iD8DBQFEsoitjV8GA4rMKUQRAt8BAJ46WNp5ueYtFGmDE9Sr3ytLRM2AKACgp6r5 UenWaQjSW2oZ0yw/RGJgIqQ= =YniF -----END PGP SIGNATURE----- --Sig_PI/0QyBgQocsOlDfIy9bt8H--
