Hi Jessica, your information looks strange. You are talking about mod_jk 1.2.22, but you present a configuration for mod_jk2, which is deprecated. mod_jk will not work with this configuration, because mod_jk uses a very different config syntax.
Strangely enough it did work - I don't know how. But I changed configs to the below in case that was part of the problem. Everything is still working the same as far as I can tell. I don't know if I need the load balancer since I only have one other worker. Will the load balancer affect performance? workers.properties # Define some properties workers.apache_log="C:\Program Files\Apache Software Foundation\Apache2.2\logs" workers.tomcat_home="C:\Program Files\Apache Software Foundation\Tomcat 5.5" workers.java_home="C:\Program Files\Java\jrockit-R27.2.0-jre1.5.0_10" ps=\ # Define 2 workers, 1 real workers using ajp13, the last one being a loadbalancing worker worker.list=worker2, worker4 # Set properties for worker2 (ajp13) worker.worker2.type=ajp13 worker.worker2.host=127.0.0.1 worker.worker2.port=8009 worker.worker2.lbfactor=1 worker.worker2.connection_pool_timeout=600 worker.worker2.socket_keepalive=1 worker.worker2.socket_timeout=60 # Set properties for worker4 (lb) which use worker2 worker.worker4.balance_workers=worker2 httpd.conf exerpt: # Config for mod_jk <IfModule !mod_jk.c> LoadModule jk_module "C:/Program Files/Apache Software Foundation/Apache2.2/modules/mod_jk.so" </IfModule> JkWorkersFile "C:/Program Files/Apache Software Foundation/Tomcat 5.5 /conf/jk/workers.properties" JkLogFile "C:/Program Files/Apache Software Foundation/Tomcat 5.5 /logs/mod_jk.log" JkLogLevel info JkMount /*.jsp worker2 JkMount /*/servlet/ worker2 JkMount /jsp-examples/* worker2 JkMount /reporting/* worker2 Although I don't know your actual configs, I assume your problem happens
when requests take longer than 300 seconds, which is the default request timeout with Apache. You can increase this with Apache Timeout directive. You can measure response times by adding "%D" to your LogFormat (microseconds response time).
I added TimeOut 1200 KeepAliveTimeout 30 To the end of httpd.conf which didn't fix the original 503 problem. I also noticed that sometimes I don't get the error at all, but the html response is incomplete. I will experiment some with %D and see if I can learn more about the problem. In the meantime, I would appreciate any ideas you all might have. Thanks, jessica Regards,
