Java heap space error in tomcat 5.5

Hi,

I am running my application under Tomcat 5.5.16 on windows server as NT service and have run into an issue where I am getting the following message "java.lang.OutOfMemoryError: Java heap space".

I tried many options to increase this heap size (before I would get an OutOfMemoryException but now it is the "OutOfMemoryError: Java heap space" error.

What I have already tried :

1.

Defined environment variables:

JAVA_OPT=-client -server -Xms512M -Xmx512M

JAVA_OPTS=-client -server -Xms512M -Xmx512M

CATALINA_OPT=-client -server -Xms512M -Xmx512M

CATALINA_OPTS=-client -server -Xms512M -Xmx512M

2. ran tomcat5w.exe -Vmargs -Xmx512M but got an error message

3. added in the registry under -

HKEY_LOCAL_MACHINE

SOFTWARE

Apache Software Foundation

Procrun 2.0

Tomcat5

Parameters

Java

Add 4 variables:

JVM Option count = 3

JVM Option number 0 = -server

JVM Option number 1 = -Xms512m

JVM Option number 2 = -Xmx512m

** What else can be done ?

Thanks
