Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Mailer: Mutt 0.91.1i Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I've got a program that i can use to panic the kernel consistently that just does a lot of FD I/O w/ the network. I don't have the ability nor familiarity w/ the kernel internals to hack source. Anyone want the source for my program that nukes the system? :) It causes some mbuf related crash... here's the message it prints on the console of the box: Out of mbuf clusters - increase maxusers! Then it does this: Fatal trap 12: page fault while in kernel mode mp_lock = 0100000002; cpuid = 1; lapic.id = 01000000 fault virtual address = 0x18 fault code = supervisor write, page not present instruction pointer = 0x8:0xf0128571 stack pointer = 0x10:0xf49ecec8 frame pointer = 0x10:0xf49ecee8 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 180 (sshd1) interrupt mask = <- SMP: XXX kernel: type 12 trap, code=0 stopped at _sosend+0x301: movl $0,0x18(%ebx) previous crashes included (instead of sshd) my program causing the system to puke I've had this problem with other systems that are not SMP also. Anything that I can provide to help? let me know. - jared To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
