Subject OutOfMemory during repair on 0.8.1
Date Wed, 06 Jul 2011 13:33:16 GMT
Hi all,

I don't seem to be able to complete a full repair on one of the nodes.
Memory consuptiom keeps growing till it starts complaining about not
having enough heap. I had to disable the automatic memtable flush, as it
was generating thousands of almost empty memtables.

My guess is that the key indexes that are kept in memory grow with each
new sstable that the repair generates. On my third attempt, I have 1102
pending tasks (which seems to be almost all SSTable build operations
mixed with a few compactions), and heap is like 80%-85% full

Is there a setting or tweak I can make? I had to up the heap from 6GB to
10GB in a 12 GB machine. I can't give it any more heap.
