Hi Paul, Jean-Frederic, to define the max TCP connections between a mod-cluster httpd and AS 7 instances, I used to have to define the following: httpd.conf: MaxClients 400 server.xml: <Connector port="8009" ... maxThreads="400"/> Is the MaxClients still the same in httpd.conf ? How is this done in AS 7 ? max-connections in the AJP connector: ? <connector name="ajp" protocol="AJP/1.3" socket-binding="ajp" max-connections="400"/> -- Bela Ban Lead JGroups (http://www.jgroups.org) JBoss / Red Hat
