Hi, I am getting very frequent panics (3 per day) on a 3.2-RELEASE server.: Fatal trap 12: page fault while in kernel mode mp_lock = 00000002; cpuid = 0; lapic.id = 00000000 fault virtual address = 0xbfca0b0c fault code = supervisor read, page not present instruction pointer = 0x8:0xc0255fa3 stack pointer = 0x10:0xcccb6f08 frame pointer = 0x10:0xcccb6f18 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 = 59793 (httpd) interrupt mask = net tty bio cam <- SMP: XXX trap number = 12 panic: page fault mp_lock = 00000002; cpuid = 0; lapic.id = 00000000 boot() called on cpu#0 # nm /kernel | grep c0255f c0255f3c T pmap_remove_pages The once the machine reboots, it often follows up (within 5 minutes) with: panic: sbflush: cc 0 || mb 0 || mbcnt 67108864 mp_lock = 00000001; cpuid = 0; lapic.id = 00000000 boot() called on cpu#0 It is a dual PIII-450 machine, with 512 MB of ram and DPT raid controller (maxusers set at 256). The machine is mildly loaded, running http, ftp, pop3, smtp, telnet... as well as a low volume NFS client and server. Any suggestions as to how to fix these panics would be greatly appreciated. If more info is needed I can probably find it. Thanks in advance, Anthony. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
