SlabAllocator OOMs much faster than HeapAllocator
-------------------------------------------------
Key: CASSANDRA-3163
URL: https://issues.apache.org/jira/browse/CASSANDRA-3163
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.0
Environment: 3 nodes, 1G heap, RF=2
Reporter: Brandon Williams
Fix For: 1.0
SlabAllocator will OOM with stress at around 5.5M rows, which in this
configuration is roughly 3.3M rows per node. Reverting to the HeapAllocator
allowed all 10M rows to finish. Examining the SA heap dump in MAT just shows
~98% of the heap is in 'remainder'
