Reposting: Apache Server - 2.2 Tomcat server 6 Jboss - 4.2
We have Web Servers talking to Jboss App Servers over mod_jk. When we do our patch or upgrade of software we do it in rolling fashion so that there is "0" customer impact. But it looks like mod_jk load balancer on Web server doesn't detect it as soon as Jboss App Server goes down. Our goal is to have 0 customer impact. So my question is what can we do to overcome this problem. Web Server sees Http Error Code 503. Information from log file: [Mon Feb 23 13:39:42.146 2009] [31682:4143745888] [error] ajp_connection_tcp_get_message::jk_ajp_common.c (966): (appfe4) can't receive the response message from tomcat, network problems or tomcat (10.10.81.89:8009) is down (errno=104) [Mon Feb 23 13:39:42.147 2009] [31682:4143745888] [error] ajp_service::jk_ajp_common.c (2097): (appfe4) Connecting to tomcat failed.
