Hello Folks, I am new to Apache httpd world and wanted to know more about it. :)
Reason I got interested in this is that, in our case, we are running multiple Tomcat JVMs under a single Apache cluster. If we shut down all the JVMs except one, sometime we get 503s. If we increase the retry interval to 180(from retry=10), problem goes away. That bring me to this question, how does Apache detects a stopped Tomcat JVM? If I have a cluster which contains multiple JVMs and some of them are down, how Apache finds that one out? Somewhere I read, Apache uses a real request to determine health of a back end JVM. In that case, will that request failed(with 5xx) if JVM is stopped? Why higher retry value is making the difference? If someone can explain a bit or point me to some doc, that would be awesome. We are using Apache 2.4.10, byrequests LB algorithm, sticky session, keepalive is on and ttl=300 for all balancer member. Thanks!
