Hi all, It is an 5.4-STABLE running on i386, date is about Aug 10 4am UTC. When I'm doing: cat /var/log/maillog | ./log.pl to do some log analysis, I panicked this system. Here are some console log and kgdb output. I'll keeping this dump for sometime, so if anyone wants any information, feel free to contact me :-) Regards, Rong-En Fan Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0x1c fault code = supervisor write, page not present instruction pointer = 0x8:0xc05123aa stack pointer = 0x10:0xea39b9cc frame pointer = 0x10:0xea39b9ec 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 = 63117 (cat) trap number = 12 panic: page fault cpuid = 0 boot() called on cpu#0 Uptime: 8d14h34m14s (kgdb) bt #0 doadump () at pcpu.h:160 #1 0xc04c141d in boot (howto=260) at /usr/src/sys/kern/kern_shutdown.c:410 #2 0xc04c17cb in panic (fmt=0xc062d55e "%s") at /usr/src/sys/kern/kern_shutdown.c:566 #3 0xc0611a8d in trap_fatal (frame=0xea39b98c, eva=0) at /usr/src/sys/i386/i386/trap.c:817 #4 0xc0611784 in trap_pfault (frame=0xea39b98c, usermode=0, eva=28) at /usr/src/sys/i386/i386/trap.c:735 #5 0xc0611369 in trap (frame {tf_fs = 24, tf_es = -899547120, tf_ds = -365363184, tf_edi -684394740, tf_esi = -684394740, tf_ebp = -365315604, tf_isp -365315656, tf_ebx = -684394740, tf_edx = 0, tf_ecx = -899544064, tf_eax = 4, tf_trapno = 12, tf_err = 2, tf_eip = -1068424278, tf_cs 8, tf_eflags = 66198, tf_esp = 1049856, tf_ss = 33554464}) at /usr/src/sys/i386/i386/trap.c:425 #6 0xc05fd51a in calltrap () at /usr/src/sys/i386/i386/exception.s:140 #7 0x00000018 in ??
