Eu estou tentando executar Cassandra. Mas estou recebendo este erro:

[root@SudeepMangu bin]# ./cassandra -f
xss =  -ea -javaagent:/home/sudeep/apache-cassandra-1.2.5-src/lib/jamm-0.2.5.jar-
XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms930M -Xmx930M -Xmn200M -
XX:+HeapDumpOnOutOfMemoryError -Xss160k

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

Eu tentei definirJAVA_OPTS para o tamanho máximo sem efeito.
