I have the problem of crashing FreeBSD 8.0-BETA2/amd64 under load on all of our SMP boxes. Is there an issue known at the moment? If not, I will prepare the kernel for whitnessing and provide more informations, if you wish.
A quick question: what is in the crash message, i.e. the backtrace? And what kind of crash is it - a panic() or a fatal trap?
On the 8-core server box, I sometimes see :
Fatal trap 12: page fault while in kernel mode fault code = supervisor read, page not present
Not sure if it's related, but on ia64 SMP (2 cpus) with 8.0-current and later with 8.0-beta1 (I havent' built beta2 yet) I'm getting crashes under load every so often. E.g buildworld -j8 is likely to crash the box. No messages, just a sudden freeze, no backtrace or panic, and then reboot.
If load is less heavy, e.g. fewer processes and some idle time, the problem doesn't seem to appear.
I'm happy to do any further testing, if suggested.
my ia64 8.0-beta1 SMP box died again on make -j8 buildworld with no panic or log entries.
Is it possible that some kernel variable needs to be increased? E.g. kern.maxproc, kern.maxfiles, etc. Or perhaps I'm talking complete rubbish..
