Tomcat behavior
Hi Folks , I have a question Folks : Does Tomcat Processes become 0 at some point if Web Application is not accessed for a while. What has happened is twice in our environment that on a Weekend Morning around 2:00 AM Tomcat Processes became 0 and they later increased to 36 processes .I found out it through a small Script that checks for the number of Apache and Tomcat processes every Minute .I found the similar behavior for Apache Twice with Apache processes becoming 0 and then after a while number changing to 8 which is normal in our environment. My question is : Does Tomcat Shuts down and restarts itself at a certain regular interval like once in a month or so .If yes then ,is there any Configuration file in Tomcat from where this can be Controlled.The same question applies for Apache --if Apache shuts and restarts itself at a certain regular interval .

Two instances of Tomcat
Hi Folks , Need some urgent help regarding setting up two instances of Tomcat .Here goes the details .We used to have Apache 1.3.23 + Tomcat 4.0.2 configuration running on Red hat 7.0.We were running two web apps under Single instance of tomcat. To make them independent we are moving towards Two instances of tomcat .So we installed second instance residing in /opt/tomcat2 directory ,first being in the directory called /opt/tomcat.Changes on server.xml were made for two different port nos.Now Everything works ok till the point when we try to generate a report in second web application it gives a Java.lang Out of Memory error.This Final report feature uses the Formula 1 Software which is a e-spreadsheet.Can any one please tell me what all settings are required for the TWO instances of tomcat.do we need TWO copies of Worker.properties files (Coz we have only one ) and if yes then what changes need to be done .Is the Java error related to JVM memory settings .We have set TOMCAT_OPTS in /etc/profile for -Xms64 and -Xmx512.
