Hi, Recently I received the following kernel panic. I was wondering if anyone has any thoughts or comments on this before I investigate further myself. The system is a dual PII 400 with 1GB ram and an internal DPT raid controller running several mirrored disks. Maxusers for the kernel is set to 256, which I know is low, but anything above that makes the system unstable (512 makes it panic every hour!). The system is running FreeBSD 3.0-Release. The system is very stable in general, and is running high load and with very diverse applications (http, https, sendmail, ftpd, ipop3d, all the possible cgi scripts in this world and many more), however a panic like this does occur once every few weeks. Sorry, no core dump for this one, since I can't replicate the scenario. Any help, comments or general information would be greatly appreciated. Fatal trap 12: page fault while in kernel mode mp_lock = 00000002; cpuid = 0; lapic.id = 00000000 fault virtual address = 0x30 fault code = supervisor write, page not present instruction pointer = 0x8:0xf020ba9d stack pointer = 0x10:0xfe3e1ebc frame pointer = 0x10:0xfe3e1ecc code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 25908 (dir) interrupt mask = <- SMP: XXX trap number = 12 panic: page fault mp_lock = 00000002; cpuid = 0; lapic.id = 00000000 boot() called on cpu#0 as the FAQ requested, here is the results of "nm" that matched most closely with the instruction pointer in the kernel. I'm guessing the "_ufsspec_write" was the funtion which actually caused the panic. f020baf4 t _ufsfifo_read f020baac t _ufsspec_close f020ba34 t _ufsspec_read f020ba70 t _ufsspec_write Thank you in advance, Anthony Bourov To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
