System: FreeBSD zfs.digiware.nl 8.2-STABLE FreeBSD 8.2-STABLE #1: Sat Feb 26 06:28:43 CET 2011 root@zfs.digiware.nl:/usr/obj/usr/src/src8/src/sys/ZFS amd64 Don't have a serial console, so I wrote down the traceback. But my guess is that that is not enough, however I needed the system so I rebooted. tb: vm_object_split at .... +0x125 vm_space_fork at .... +0x3f7 fork1 at .... +0x6a9 fork at .... +0xee syscall_entr at .... +1c syscall at .... +4c rip = 0x8006bc39c rsp = 0x7fffffffe9d8 rbp = 0x800a04470 It looks a lot like what I find on http://people.freebsd.org/~pho/stress/log/kostik079.html But my system is amd64, with 8Gb RAM and is fully ZFS based with swap on 2 gpt freebsd-swap partitions. System crashed last night around 1:30, which is when a few large rsync backups are coming in. Would I be able to call doadump to obtain something usefull afterward (provided I have savecore set?) --WjW
