[opencms-dev] Possible Memory Leak in version 5.0.1

[Eke, Kemi]

Hi List

I am currently running Opencms 5.0.1 on RH Linux Advanced Server v3, on
server hardware with 1 GB of RAM. I have 600 users hitting the site and 5
editors. Every one to two days or so for the past month or so, I have had to
restart Tomcat 4.1.30 as I would get OutOfMemory errors with it causing
OpenCMS to stop functioning.  I am aware that one can add parameters to
CATALINA_OPTS to allow Java to use a certain size of memory viz -Xmx and
-Xms. I have now written a "restart" script for Tomcat which runs overnight
via cron:

#! /bin/bash
#
# name:         tomcat_refresh.sh
# description:  Tomcat REFRESH Script on Linux to solve OutOfMemory Errors
with Opencms
#
#
#
 

JAVA_HOME=/usr/java/j2sdk1.4.1_02
CATALINA_HOME=/opt/jakarta-tomcat-4.1.27
CATALINA_OPTS=-Dfile.encoding=UTF-8 -Xms128m -Xmx512m
export JAVA_HOME CATALINA_HOME CATALINA_OPTS
 

$CATALINA_HOME/bin/shutdown.sh;
sleep 25;
$CATALINA_HOME/bin/startup.sh;

Has anyone else experienced these memory problems with Opencms 5.0.1? Are
there any other specific optimisations that can be done to allow the system
to run more efficiently that others know of? I presume the information in
this post refers to an older version of Opencms:
