This is part of one server.xml

This is the second tomcat

This is part of the apache conf

We are trying to test this with 600 clients , when we reach 200 ,
everything gets stuck....
any ideas?
Thanks in advance four your help

Hi Julio,
What is the MaxClients setting in httpd.conf?
Also is there a central Database - that could also be a possible
