Max: load: 1.62 cmd: ifconfig 920 [runnable] 0.00u 96.02s 98% 920k That's what ^T says. I'm going to reboot and ktrace it now. So here's the last few lines of the ktrace: 944 ifconfig CALL modstat(0x10a,0x7fffffffe280) 944 ifconfig RET modstat 0 944 ifconfig CALL modfnext(0x10a) 944 ifconfig RET modfnext 267/0x10b 944 ifconfig CALL modstat(0x10b,0x7fffffffe280) 944 ifconfig RET modstat 0 944 ifconfig CALL socket(0x2,0x2,0) 944 ifconfig RET socket 3 944 ifconfig CALL ioctl(0x3,SIOCIFCREATE,0x514ce0) l# lsof -p 944 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME ifconfig 944 root cwd VDIR 0,77 512 16525 /root ifconfig 944 root rtd VDIR 0,77 512 2 / ifconfig 944 root txt VREG 0,77 80296 48 /sbin/ifconfig ifconfig 944 root txt VREG 0,77 192688 116 /libexec/ld-elf.so.1 ifconfig 944 root txt VREG 0,77 7424 24794 /lib/libipx.so.3 ifconfig 944 root txt VREG 0,77 1083208 24786 /lib/libc.so.6 ifconfig 944 root 0u VCHR 0,93 0t2101 93 /dev/ttyp0 ifconfig 944 root 1u VCHR 0,93 0t2101 93 /dev/ttyp0 ifconfig 944 root 2u VCHR 0,93 0t2101 93 /dev/ttyp0 ifconfig 944 root 3u IPv4 0xffffff002d459130 0t0 UDP *:* Sorry I don't have physical access so I can't break into the kernel debugger right now. cc Your #1 Fan -- Chris Chen <[EMAIL PROTECTED]> "I want the kind of six pack you can't drink." -- Micah _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
