Application Logout Issues
Users keep getting logged out of our Java apps within a minute or two for no
apparent reason.Below are my settings, any help would be appreciated.
I am running Red Hat Linux 2.6.18-164.el5 #1 SMP x86_64 x86_64 x86_64
GNU/Linux with Tomcat 6 as seen below:
# /opt/tomcat/bin/version.sh
Using CATALINA_BASE: /opt/tomcat
Using CATALINA_HOME: /opt/tomcat
Using CATALINA_TMPDIR: /opt/tomcat/temp
Using JRE_HOME: /usr/java/jdk1.6.0_16
Server version: Apache Tomcat/6.0.20
Server built: May 14 2009 01:13:50
Server number: 6.0.20.0
OS Name: Linux
OS Version: 2.6.18-164.el5
Architecture: amd64
JVM Version: 1.6.0_16-b01
JVM Vendor: Sun Microsystems Inc.
My system has 6GB of RAM.
I have tried various JAVA_OPTS, the most current one is at the bottom:
#JAVA_OPTS="$JAVA_OPTS -Xmx3072M -Xms3072M"
#JAVA_OPTS="$JAVA_OPTS -Djava.awt.headless=true -Dfile.encoding=UTF-8
-server -Xms2048m -Xmx2048m -XX:NewSize=1024m -XX:MaxNewSize=1024m
-XX:PermSize=1024m -XX:MaxPermSize=1024m -XX:+DisableExplicitGC"
#JAVA_OPTS="$JAVA_OPTS -Djava.awt.headless=true -Dfile.encoding=UTF-8
-server -Xms2048m -Xmx2048m -XX:NewSize=1024m -XX:MaxNewSize=1024m
-XX:PermSize=1024m -XX:MaxPermSize=1024m -XX:+CMSClassUnloadingEnabled
-XX:+CMSPermGenSweepingEnabled -XX:+UseConcMarkSweepGC"
#JAVA_OPTS="$JAVA_OPTS -Djava.awt.headless=true -Dfile.encoding=UTF-8
-server -Xms2048m -Xmx2048m -XX:NewSize=1024m -XX:MaxNewSize=1024m
-XX:PermSize=1024m -XX:MaxPermSize=1024m -XX:+UseConcMarkSweepGC"
JAVA_OPTS="$JAVA_OPTS -Djava.awt.headless=true -Dfile.encoding=UTF-8 -server
-Xms2048m -Xmx2048m -XX:NewSize=1024m -XX:MaxNewSize=1024m
-XX:PermSize=1024m -XX:MaxPermSize=1024m"
My timeout settings are as follows:
# grep -i timeout conf/*
conf/server.xml: connectionTimeout="20000"
conf/server.xml: acceptCount="10" debug="0"
connectionTimeout="60000"/>
conf/web.xml: <!-- You can set the default session timeout (in minutes) for
all newly -->
conf/web.xml: <session-timeout>30</session-timeout>
Thanks!

All of your apps? How many? All different? Do they share some
configuration?
The reason for this is likely to be found in your applications, not in
the OS or the JVM.

Your JAVA_OPTS are most likely absolutely irrelevant.

Irrelevant.

Relevant, but this is the default - 30 minutes.
