Just found this on one of my 2.0.36 boxes. I do not know what
exactly happened, but klogd was dead and that's only retrieved
from dmesg buffer (I added ksymoops output). I do not know is
it related, but kerneld also is dead and I cannot load it anymore.
The box has light usage as dialin/ftp/www/firewall server and
also runs q2 and q1 dedicated servers.
What can it be? This is not first report about tcp oopses on 2.0 kernel,
as I can see.
