All, I made a simple change to the Apache HTTPD configs - I reduced the number of loaded modules - and then stopped and started Apache. On the QA environment, Tomcat did not need a restart. On the PROD (production) environment, soon after Apache was restarted, the application URLs resolved okay. But a minute later, I received an Internal Server Error from Apache. Hitting Tomcat directly did not work either. It required a Tomcat restart to start receiving the URLs again. I am not sure why the two environments behaved differently. It was not my browser cache, 'cause I reloaded the URL. It was not the loadbalancer RAM Cache as the loadbalancer RAM Cache is disabled. Didn't find anything in the logs. I wanted to know your thoughts.
Thanks. -Shanti
