I have figured this out, late to reply.. Reason was I was running Java 32 bit on a 64 bit machine. Don't know the internals, why cassandra bheaved differently with java and machine architecture. Thanks, Ashish tjake on "Cassandra starting with exceptions" http://www.datastax.com/support-forums/topic/cassandra-starting-with-exceptions#post-1952 Mon, 21 May 2012 13:19:50 +0000 tjake 1952@http://www.datastax.com/support-forums/ In unix this means the OS limits need to be raised for that user. <a href="http://wiki.apache.org/cassandra/FAQ#memlock" rel="nofollow">http://wiki.apache.org/cassandra/FAQ#memlock</a> I'm not sure what this translates to for windows.

For now you should run with the latest version of Java 6.
