Glassfish v3 failure when startup. "Cannot allocate memory "

Question

It is clear in this Question

https://serverfault.com/questions/210275/fail-to-start-glassfish-3-1-java-io-ioexception-error-12-cannot-allocate-mem

But in my case,I have a 512M memory Ubuntu 10.04 vps.It seems that I don't need to change any configure.But when start the server,I got this exception

VM failed to start: java.io.IOException: Cannot run program "/usr/lib/jvm/java-6-sun-1.6.0.22/bin/java" (in directory "/home/glassfish/glassfish/domains/domain1/config"): java.io.IOException: error=12, Cannot allocate memory

So,I set

<jvm-options>-Xmx512</jvm-options>

to

<jvm-options>-Xmx400</jvm-options>

The exception remains.What did I do something wrong?

Keep in mind that Java requires that heap space be allocated from one contiguous memory space, so your memory may be fragmented to the point where the process cannot acquire a space big enough to initialize (although it will not allocate the -Xmx or even the -Xms amount of memory right off the bat.

See this stackoverflow post for one potential solution:
