Hi,
>From memory, a 503 using a direct connection to tomcat HTTP connector means
that Tomcat server connector cannot accept any more connections.
I think you should look at the server.xml file in tomcat and configure a
higher number of threads and may be accept. You can copy your current
server.xml here if you want.
Your memory and machine looks OK to me.
Hope this help,
Fred.
