Linux out of memory on VPS

I have a OpenVZ VPS running CentOS 6.3 64 bit and when I try to install JRE 7 64bit using the command:

rpm -Uvh java.rpm

It gives me this error:

Preparing...                ########################################### [100%]
   1:jre                    ########################################### [100%]

        rt.jar...

        localedata.jar...
Error: Could not open input file: /usr/java/jre1.7.0_09/lib/ext/localedata.pack

I then tried the command:

java -version

And it gives me this error:

Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine
Error: A fatal exception has occurred. Program will exit.

Why does this happen if I have more than enough RAM on the VPS to run this (1GB)? Could it be an issue with the host node of the VPS?

Thanks

    Those "errors" are spurious and can be ignored. The real problem is you don't have as much memory in that VPS as you think you do. Post a copy of your `/proc/user_beancounters`. – Michael Hampton Dec 05 '12 at 21:22
  • I have added a screenshot of the user_beancounters via a link – user1710563 Dec 05 '12 at 21:26
  • Yep, it's the same problem, and the same answer as in the question I flagged this as a duplicate of. – Michael Hampton Dec 05 '12 at 21:27
  • Java's default heap size of 128M pushes you over your guaranteed memory limit. Therefore the memory allocation can fail if the host is overcommitted. You will need to use the `-Xms` and `-Xmx` options to run your JVM, or (even better) switch to anything but OpenVZ. – Michael Hampton Dec 05 '12 at 21:42

Depending on what you want to do I'd suggest stop using OpenVZ and use some real virtualization solution like KVM.

Try running you java app using this command:

java -Xms16m
