Hi Mike, If you are not explicitly setting the JVM initial heap size and maximum heap size then they will take the default values which are quite small (64MByte max I think?).
If you want the JVM to use more of the system's memory then start it up using the switches: -Xms <initial heap size> -Xmx <maximum heap size> (This is for the Sun 1.3 JVM, but I expect the HP JVM has an equivalent) so for 100MB initial heap, 150MB maximum heap you would change your startup script to override the defaults: java -Xms100M -Xmx150M <classname> In catalina.sh (Tomcat 4) there is an environment variable CATALINA_OPTS that will add extra parameters to the java command so I just set CATALINA_OPTS=" -Xms500M -Xmx1000M". There may be a similar option in Tomcat 3.2.3. Hope this helps, Chris -----Original Message----- From: Michael S.
