Set ddb.console=1 in sysctl.conf and reboot (you can't change this on a running system with securelevel=1 as is normally set), if/when it happens again you can try breaking into DDB (ctrl+alt+esc from glass console, BREAK from serial console) and you may be able to get more information about what's happening (trace/ps would be good places to start - serial console would let you paste the output into email which would be helpful if you need other people to look at it).
Re: Boxes hanging intermittently. Anybody seen such ?
Is there a set time when this will happen, say after it's been up for ~5 hours, or is it completely random, 2 days one time, 1 hour another -Original Message- From: owner-m...@openbsd.org [mailto:owner-m...@openbsd.org] On Behalf Of Andres Salazar Sent: 17 August 2009 01:29 To: misc@openbsd.org Subject: Boxes hanging intermittently. Anybody seen such ? Hello, During the past week two boxes two boxes on the same network have stopped responding, they carry OpenBSD 4.5 i386 and I have logged at every possible log to find out why this occurs however I havent been able to spot anything unusual. All of the sudden they just stop responding requests. What these freezes do have in common is that when the boxes are reached via the KVM they present the login screen, they allow text to be entered in the login field... but upon hitting enter for it to ask the password thats when it just hangs. Iam afraid this will keep on happening and I woudl like to know if anybody has experienced this before.. these have been perfectly working boxes and it would be just odd both would have the same problem in the same few days. Upon a reboot everything returns to normal. Thank you. Andres
Re: Boxes hanging intermittently. Anybody seen such ?
For me the same issue on a couple of boxes. The only common thing for me is : - Soekris - SpamAssassin - Clamav-milter - PF + spamd - Sendmail Most of the boxes runs without any problems for years and sometimes it dies...

By your description, particularly the use of the term "field," it seems you're running xdm (graphical login). You did *NOT* mention the specific arch where you are having the problem, and you did *NOT* mention the types of input/output devices on the system? You did *NOT* mention the specific brand and model of KVM you're using, or how you have things wired (i.e. PS/2 connectors, USB connectors, $OTHER connectors, or the dreaded USB-to-PS/2 adapters)? As for things going bad upon switching from one OpenBSD i386 system to another via a Belkin F1D108-OSD 8-port KVM, yes, I've seen it happen. The cause is using dodgy USB-to-PS2 adapters to connect the KVM to machines that do not have PS2 ports. On occasion, it works fine, but often it does crazy things and then locks up. In these cases, the keyboard still sorta works for a bit, and occasionally the mouse goes on mad clicking spree, until the whole thing locks up. --What I've seen seems real similar to what you very vaguely described. -- J.C.

Those setups are definitively problematic. :)
