Hello, Before I discuss my problem here is a short info on my server: ------------------------------------------------------------------------------------ jxm203 /kernel: FreeBSD 2.1.5-RELEASE #0: Fri Sep 13 20:18:27 EDT 1996 jxm203 /kernel: mcellroy@jxm203:/usr/src/sys/compile/KERNEL_9_13_1996 jxm203 /kernel: CPU: i486DX (486-class CPU) jxm203 /kernel: real memory = 37748736 (36864K bytes) jxm203 /kernel: avail memory = 34893824 (34076K bytes) jxm203 /kernel: Probing for devices on the ISA bus: jxm203 /kernel: sc0 at 0x60-0x6f irq 1 on motherboard jxm203 /kernel: sc0: VGA color <16 virtual consoles, flags=0x0> jxm203 /kernel: ed0 at 0x280-0x29f irq 5 on isa jxm203 /kernel: ed0: address 00:80:1e:00:52:86, type NE2000 (16 bit) jxm203 /kernel: sio0 at 0x3f8-0x3ff irq 4 on isa jxm203 /kernel: sio0: type 16550A jxm203 /kernel: sio1 at 0x2f8-0x2ff irq 3 on isa jxm203 /kernel: sio1: type 16550A jxm203 /kernel: pca0 on motherboard jxm203 /kernel: pca0: PC speaker audio driver jxm203 /kernel: fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa jxm203 /kernel: fdc0: NEC 765 jxm203 /kernel: fd0: 1.44MB 3.5in jxm203 /kernel: wdc0 at 0x1f0-0x1f7 irq 14 on isa jxm203 /kernel: wdc0: unit 0 (wd0): <Maxtor 7850 AV> jxm203 /kernel: wd0: 814MB (1667232 sectors), 1654 cyls, 16 heads, 63 S/T, 512 B/S jxm203 /kernel: npx0 on motherboard jxm203 /kernel: npx0: INT 16 interface ------------------------------------------------------------------------------------ And here is my kernel config file: ------------------------------------------------------------------------------------ # # GENERIC -- Generic machine with WD/AHx/NCR/BTx family disks # # $Id: GENERIC,v 1.46.2.14 1996/07/11 01:09:47 jkh Exp $ # # PC compatible computer machine "i386" cpu "I486_CPU" # Kernel name ident "KERNEL_9_13_1996" # Sets max tables maxusers 48 # This is where to look for the bootstrap stuff config kernel root on wd0 # Filesystems included in kernel # Other types are loaded by lkm # options FFS #Berkeley Fast Filesystem options NFS #Network Filesystem options PROCFS #Process filesystem options MSDOSFS #MSDOS Filesystem # Other system options options INET #InterNETworking options "COMPAT_43" #Compatible with BSD 4.3 options COMPAT_LINUX # Able to run linux binaries options BOUNCE_BUFFERS #include support for DMA bounce buffers options UCONSOLE #Allow users to grab the console options KTRACE #Allow system process tracing # System V stuff(shared mem, semiphores, and messages) options SYSVSHM options SYSVSEM options SYSVMSG # Allow user-mode programs to manipulate their local descriptor tables. # This option is required for the WINE Windows(tm) emulator, and is # not used by anything else(that we know of). # options USER_LDT #allow user-level control of i386 ldt # ISA bus controller controller isa0 controller eisa0 # Floppy drive device controller controller fdc0 at isa? port "IO_FD1" bio irq 6 drq 2 vector fdintr # Floppy drive disk fd0 at fdc0 drive 0 # Hard disk controller controller wdc0 at isa? port "IO_WD1" bio irq 14 vector wdintr # Hard drive disk wd0 at wdc0 drive 0 # syscons is the default console driver, resembling an SCO console device sc0 at isa? port "IO_KBD" tty irq 1 vector scintr # Enable this and PCVT_FREEBSD for pcvt vt220 compatible console driver #device vt0 at isa? port "IO_KBD" tty irq 1 vector pcrint #options "PCVT_FREEBSD=210" # pcvt running on FreeBSD 2.1 #options XSERVER # include code for XFree86 # If you have a ThinkPAD, uncomment this along with the rest of the PCVT lines #options PCVT_SCANSET=2 # IBM keyboards are non-std # We love X :) options XSERVER # include code for XFree86 # Mandatory, don't remove # Floating point device # device npx0 at isa? port "IO_NPX" irq 13 vector npxintr # Serial ports device sio0 at isa? port "IO_COM1" tty irq 4 vector siointr device sio1 at isa? port "IO_COM2" tty irq 3 vector siointr # Order is important here due to intrusive probes, do *not* alphabetize # this list of network interfaces until the probes have been fixed. # Right now it appears that the ie0 must be probed before ep0.

It becomes wedged so hard that I can't even get through from my terminal on the serial port. Also there are no messages of any kind in syslog, and the hard drive is not active. This can happen under extreme load or no load at all, when people are logged in or no one is logged in. I have read through the mailing lists and have found people with problems similar to mine, but I have not seen a solution. I *need* a fix for this because my nfs and web service depend on it. Thank you for your attention. Jon McEllroy Systems Administrator Deparment of Mathematics Penn State University +1-814-865-2778 mcellroy@math.psu.edu
