However from the JVM Heap Size section here
For a rough rule of thumb, Cassandra's internal datastructures will require about memtable_throughput_in_mb * 3 * number of hot CFs + 1G + internal caches.
So you have (32 * 3 * 12) = 1152MB for the CF's plus the 1G + internal caches. Running inside of 1 or 1.5 GB is probably not going to work.
The simple solution may be to reduce the number of CF's.
Looks like 0.7.0 will have per CF thresholds, but you will still need more memory and/or less CF's I think.
