Obviously apache can't connect to tomcat. Any firewall/load balancer changes maybe done last night between apache and tomcat? Can you access tomcat apps bypassing apache? Can you telnet to tomcat server on the tomcat port from the apache? Any errors in the tomcat log? Have you tried restarting tomcat?
