Dear Users!

Firstly sorry my bad English.
I read Stephans great documentation at http://wiki.media-style.com/display/nutchDocu/.
I maked a frontend (P4 3 GByte RAM, Tomcat 5.5.7 java 1.4.08) with 3 backend with 12 million pages ( 4million / backend AMD64 4 GByte RAM 64 bit linux with jdk 1.5_03).


When I start using it with 3-5 queries / sec, after 1-2 minute the frontend does'nt answer to the requests.
In the Tomcat manager / status I see there is many thread busy (150 and it increasses, now 241), and these are with Stage 'S' (Service).


The backend with usage: top 40-60 % CPU.
The frontend with usage: 5% CPU.

Have you any idea what is the problem?

Best Regards,
   Ferenc
