I am attempting to install Glassfishv3 on my Ubuntu (8.04) VPS using Java 1.6.

I initially tried starting the server using:

asadmin start-domain

and received the following error message:

JVM failed to start: com.sun.enterprise.admin.launcher.GFLauncherException: The server exited prematurely with exit code 1. Before it died, it produced the following output:

Error occurred during initialization of VM Could not reserve enough space for object heap

Command start-domain failed.

I attempted to run it again and received a different message:

Waiting for DAS to start Error starting domain: domain1. The server exited prematurely with exit code 1. Before it died, it produced the following output:

Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine.

Command start-domain failed.

If I run cat /proc/meminfo I get the following (all other values are 0kB):

MemTotal:  1310720 kB 
MemFree:   1150668 kB
LowTotal:  1310720 kB 
LowFree:   1150668 kB

I have checked the contents of glassfish/glassfish/domains/domain1/config/domain.xml and the JVM setting is:

-Xmx512m

Any help on resolving this problem would be appreciated.
