Hi Chuck, Thanks for the prompt reply. Please refer to the following requested info:
Tomcat version: Tomcat: 5.5.31 JVM version: gij (GNU libgcj) version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3) If the JAVA_OPTS affects the shutdown process, then I have to find out what is the best setting for this env variable since I often encounter the server panic during shutdown. What do you think? Both env variables ( JAVA_OPTS and CATALINA_OPTS) are used throughout the catalina.sh file so I cannot remove one and retain the other. Previously, JAVA_OPTS is set to '-Xmx512m -XX:+AggressiveHeap' so I thought increasing the heap size to 1024 will resolve the server panic. I have two tomcat seated on two different machines. When I increased the JVM heap size on the first machine and tried to restart a couple of times, I didn't encounter any server panic. But when I tried on the other machine, even on the first attempt, the server goes to panic. The two machines has the same specs. Both tomcats contain the same web application. Do you think it is really the tomcat settings that causes the server to panic? Should I consider using -server mode in the JAVA_OPTS?
