[cobalt-developers] RaQ550 rebooted, weird line in httpd's error log, kernel panic also :*(

["Dave @ The Hostworks" <lists@xxxxxxxxxxxxxxxx>]

Well about an hour ago I noticed one of our RaQ units rebooted for no
reason, digging through logs, I found this entry right before it rebooted.

[Tue Aug  5 14:42:05 2003] [error] [client 64.xxx.xx.67] File does not
exist: /home/.sites/123/site19/users/oze/web/hlstats/hlstats.php

[Tue Aug  5 14:56:38 2003] [warn] NameVirtualHost 204.xx.xx.34:80 has no
VirtualHosts


And the same line was found in access log at the same time..

Anyone care to share some insight to what might have happened? It was a
kernel panic. /var/log/kernel shows:
