It happens only at ip routers and probably something routing dependent. All process stop but it still does all in-kernel ip tasks like accepts connections (but with nothing happening after that) and responses to ping requests. Of course, as routing daemons are dead no routing is performed. There is no NFS on that machine. >Jan 20 09:01:23 lightning /kernel: FreeBSD 2.1.6-RELEASE #1: Tue Jan 14 12:32:48 MSK 1997 >Jan 20 09:01:23 lightning /kernel: alexis@lightning.ww.net:/home/src/FreeBSD-2.1.6/src/sys/compile/LIGHTNING >Jan 20 09:01:23 lightning /kernel: CPU: i486DX (486-class CPU) >Jan 20 09:01:23 lightning /kernel: Origin = "AuthenticAMD" Id = 0x4f4 >Jan 20 09:01:23 lightning /kernel: real memory = 12582912 (12288K bytes) >Jan 20 09:01:24 lightning /kernel: avail memory = 10919936 (10664K bytes) >Jan 20 09:01:24 lightning /kernel: Probing for devices on PCI bus 0: >Jan 20 09:01:24 lightning /kernel: chip0 <SiS 85c496> rev 2 on pci0:5 >Jan 20 09:01:24 lightning /kernel: Probing for devices on the ISA bus: >Jan 20 09:01:24 lightning /kernel: lpt0 at 0x378-0x37f irq 7 on isa >Jan 20 09:01:24 lightning /kernel: lpt0: Interrupt-driven port >Jan 20 09:01:24 lightning /kernel: lp0: TCP/IP capable interface >Jan 20 09:01:24 lightning /kernel: sio0 at 0x3f8-0x3ff irq 4 on isa >Jan 20 09:01:24 lightning /kernel: sio0: type 16550A >Jan 20 09:01:24 lightning /kernel: sio1 at 0x2f8-0x2ff irq 3 on isa >Jan 20 09:01:24 lightning /kernel: sio1: type 16550A >Jan 20 09:01:24 lightning /kernel: dgb0: PC/Xe 64/8K (windowed) >Jan 20 09:01:24 lightning /kernel: dgb0 at 0x320-0x323 maddr 0xd0000 msize 8192 on isa >Jan 20 09:01:24 lightning /kernel: dgb0: 8 ports >Jan 20 09:01:24 lightning /kernel: wdc0 at 0x1f0-0x1f7 irq 14 flags 0x80ff80ff on isa >Jan 20 09:01:25 lightning /kernel: wdc0: unit 0 (wd0): <ST51080A>, 32-bit, multi-block-32 >Jan 20 09:01:25 lightning /kernel: wd0: 1033MB (2116800 sectors), 2100 cyls, 16 heads, 63 S/T, 512 B/S >Jan 20 09:01:25 lightning /kernel: fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa >Jan 20 09:01:25 lightning /kernel: 1 3C5x9 board(s) on ISA found at 0x300 >Jan 20 09:01:25 lightning /kernel: ep0 at 0x300-0x30f irq 10 on isa >Jan 20 09:01:25 lightning /kernel: ep0: aui/bnc[*BNC*] address 00:20:af:15:52:c4 >Jan 20 09:01:25 lightning /kernel: npx0 on motherboard >Jan 20 09:01:25 lightning /kernel: npx0: INT 16 interface >Jan 20 09:01:25 lightning /kernel: IP firewall initialized, unlimited logging >Jan 20 09:01:25 lightning /kernel: WARNING: / was not properly dismounted. >Jan 20 09:02:10 lightning telnetd[147]: connect from Simferopol2.ww.net >Jan 20 09:02:40 lightning login: login from Simferopol2 as alexis >Jan 20 09:03:46 lightning doas: alexis as root on ttyp0: /usr/local/bin/tcsh >Jan 20 09:05:01 lightning gdc: performing a "gdc running" command for user root >Jan 20 09:10:00 lightning gdc: performing a "gdc running" command for user root >Jan 20 09:15:00 lightning gdc: performing a "gdc running" command for user root >Jan 20 09:25:00 lightning last message repeated 2 times >Jan 20 09:35:00 lightning last message repeated 2 times >Jan 20 09:45:00 lightning last message repeated 2 times >Jan 20 09:55:00 lightning last message repeated 2 times >Jan 20 10:05:00 lightning last message repeated 2 times >Jan 20 10:15:01 lightning last message repeated 2 times >Jan 20 10:25:00 lightning last message repeated 2 times >Jan 20 10:35:00 lightning last message repeated 2 times >Jan 20 10:45:00 lightning last message repeated 2 times The question is that whether it is well known problem with a trivial fix so I would not waste my time investigating?
