I installed the fedora-ds successfully. On starting the console, I get the following error messages:
[root@neutron fedora-ds]# ./startconsole -u admin -a http://neutron:21821/
GC Warning: Out of Memory!  Returning NIL!
Exception in thread "main" GC Warning: Out of Memory!  Returning NIL!
java.lang.LinkageError: unexpected exception during linking: com.netscape.management.client.console.Console
GC Warning: Out of Memory!  Returning NIL!
*** Catastrophic failure while handling uncaught exception.
GC Warning: Out of Memory!  Returning NIL!
Does this indicate that the sytem has insufficient RAM, or is it something else that I am missing.
