Hi,
when burning a DVD today, our new Debian workstation suddenly froze. I could
move the mouse cursor, but the system did not respond to any keypresses
(even magic sysrq). I could not ssh to the box and it did not even respond
to ping.
With no other options, I powered it down and back up again, and it come up
nicely. None of the logfiles show nothing interesting, at some point the
logging just stops.
How can I investigate this further? I already burned and erased a DVD-RW
dozens of times in a loop without a problem. Currently I'm running
memtest86. I suspect some kind of hardware problem, because our other Debian
workstations have never done this kind of thing.
The machine is a Dell Precision 690 with 2 dual-core Xeon processors, 4 GiB
of memory and two SAS hard drives, running Debian Lenny.
I've experienced these same symptoms (when simply surfing the web,
when my system is under a heavy memory load, not when burning a DVD)
in Unstable, running 2.6.2[0-4] kernels, but, like you, haven't been
able to find a cause. Hasn't happened with 2.6.2[567] kernels, yet.
Of course, the kernel might have nothing to do with the error...
My suspicion, though, has been memory overcommit issues, since I
have this in my /etc/sysctl.conf :
vm.overcommit_memory = 2
