You need to gather more information to determine what the problem is. The error message simply says you have run out of connections. When the problem happens, use "netstat" to show all the connections and count how many of them are connected to the Tomcat server. This should give you an idea which number you should look at in the configuration file.
If you just want to play around without waiting for the problem to happen. Check the Tomcat document and examine the parameters
