Server is visible (traceroute/ping, see below) but
web services are _extremely_ slow. (like 2 minutes
until the page appears).
Lookup (be seq number): approx 3 minutes until
an error page appears:
<cite>
Error 500
Internal Server Error
couldn't spawn child process: /www/www/cgi-bin/access.cgi

Note the last line!
Likely there are zillions of processes.
Check the load and process table!
