Not sure what happened here. The app was working just fine until today. I am getting a 503 Service temporarily unavailable error when trying to connect to a tomcat site using Apache as the front end and mod_jk connectors. I have verified that tomcat is running on the correct ports using:netstat -atp | grep java and it is listening on the correct ports. I see no errors in the message logs ( we are on CentOS by the way ) but I do see:

in the mod_jk.log file. Apache is running. I am stumped but really need to get this back running if anyone outhere is more experienced at tomcat and apache connectors than I am, which wouldn't take much ;-)
Cheers,
