Brandon Williams updated CASSANDRA-3163: ---------------------------------------- Attachment: system.log.gz Here's a system.log with your extra debug statements and Memtable set to DEBUG. It OOM'd many times, but never actually dumped. > 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 > > Attachments: system.log.gz > > > 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' -- This message is automatically generated by JIRA.
