This looks like CASSANDRA-4201 where map() was failing with oom under 32

Jonathan provided a patch for that. You can apply it on top of 1.1.

8G, by default the jvm was taking 2G, and I had this error
even with 1G, I had the error, finally 500M made it work

How much memory do you have on the box?
It seems you need more memory.
