dying on 3.4.1 toolkit host, web100srv not running

Hi,

Also is there anything in /var/log/ndt/fakewww_error.log? I noticed on one of 
our toolkit hosts it was down today and this was the last line in this log: 

[Tue Dec 02 08:35:29 2014] [error] [client 180.76.6.134] Permission denied: 
path not allowed: /robots.txt

Curious if you have anything similar, possibly a web crawler is confusing 
fakewww?

Thanks,
Andy
