error running java application

I am trying to run a java application with the following script but i am having error.

script

Code:

#!/bin/sh

nohup java -jar "node-alerter.jar" & > node-log.log

pid=$!

echo ${pid} > mydaemon.pid

and the error i am getting is

Code:

Error occurred during initialization of VM

Could not reserve enough space for object heap

Could not create the Java virtual machine.

This error raises even if i run any java application directly. What to do?

The server is already installed with java the command

Code:

which java

returns the follwing result

Code:

/usr/java/jdk1.5.0_12/bin/java

and there is already tomcat server running there (which is acting as primary server for this machine).

Sounds like you're out of either memory or hard disk space.
