Tomcat 5 / Nutch web gui timeout "blank page"

[Håvard W. Kongsgård]

I have a problem with my Nutch web gui sometimes returning empty pages 
when I do a search. In Nutch 0.7 this was fixed by giving 
ipc.client.timeout a higher value in my webapp/ROOT/ 
WEB-INF/classes/hadoop-site.xml but this has no effect in nutch 0.8.1, 
the nutch web gui still times out after about 30s.
