Hi

I got this oops on my machine tonight.

I don't know what query to BIND caused it, but I've got an oops like this before!

[root@binhex gdh]# ksymoops  -k /proc/ksyms -l /proc/modules -o /lib/modules/2.4.22-1.2174.nptl/ -m /boot/System.map-2.4.22-1.2174.nptl  < blah
ksymoops 2.4.5 on i586 2.4.22-1.2174.nptl.  Options used
     -V (default)

     -l /proc/modules (specified)
     -o /lib/modules/2.4.22-1.2174.nptl/ (specified)
     -m /boot/System.map-2.4.22-1.2174.nptl (specified)
