In-Reply-To: <199910292032.PAA92238@ns1.cioe.com> Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-isp@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hi Guys, thanks for the input on "FreeBSD & MySQL" topic. Here comes another problem: I recently purchased this PIII-600mhz with 128MB RAM + a ASUS P3BF motherboard + adaptec 2940U2W controller and two IBM 10K disks. I installed FreeBSD3.3-stable on it, well, the ftp install program was once core dumped (signal 11) for some reasons, but it went ok after retry. So now I started to use the machine and it constantly crashs. The crash usually kicks in after a process exit. Below is the crash dump that I happened to catch: IdlePTD 2686976 initial pcb at 223a50 panicstr: page fault panic messages: --- Fatal trap 12: page fault while in kernel mode fault virtual address = 0x80004 fault code = supervisor read, page not present instruction pointer = 0x8:0xc01d5af6 stack pointer = 0x10:0xcaffaf18 frame pointer = 0x10:0xcaffaf30 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 = 2 (pagedaemon) interrupt mask = net tty bio cam trap number = 12 panic: page fault #0 boot (howto=256) at ../../kern/kern_shutdown.c:285 #1 0xc01446f8 in at_shutdown ( function=0xc02054ba <__set_sysinit_set_sym_memdev_sys_init+1050>, arg=0xcaff2d00, queue=-889213220) at ../../kern/kern_shutdown.c:446 #2 0xc01d7245 in trap_fatal () #3 0xc01d6f23 in trap_pfault () #4 0xc01d6bc6 in trap () #5 0xc01d5af6 in pmap_changebit (pa=47714304, bit=32, setem=0) at ../../i386/i386/pmap.c:624 #6 0xc01d5d2f in pmap_clear_reference (pa=47714304) at ../../i386/i386/pmap.c:3204 #7 0xc01bdb05 in vm_pageout_scan () at ../../vm/vm_pageout.c:746 #8 0xc01be662 in vm_pageout () at ../../vm/vm_pageout.c:1382 #9 0xc01372e2 in kproc_start (udata=0xc021b028) at ../../kern/init_main.c:303 #10 0xc01cd99a in fork_trampoline () ----- Does it sound like a detect RAM to those of you who can read the dump?
