I've two servers (A, B). On "A" I've Apache as a Web-Server for a Tomcat Application and on Server "B" I've another Tomcat Application which is also entertained by the same Apache on server "A" additionally I'm using AJP connector also to find out which request goes to what server. Problem comes in when there are approx 60 to 70 users which access application on server B. I've 4GB stick plus quad core. As per the log there is no memory error, it says some connection error. Please suggest the best configuration for approx 100 users or so.

    "it says some connection error" - this is really not helpful. What error do you get? What kind of applications are we talking about? You need to provide more information if you expect anyone to help you. – germi Apr 24 '15 at 07:08
