Subject Nodes frozen in GC
Date Sat, 05 Mar 2011 21:34:21 GMT
Hello

I have cluster of 3 cassandra 0.7.3 nodes, and some times nodes a frozen. As
i understand this because GC, in this moment i see

INFO [ScheduledTasks:1] 2011-03-05 15:21:23,524 GCInspector.java (line 128)
GC for ConcurrentMarkSweep: 18052 ms, -997761672 reclaimed leaving
5796586088

How can i reduce this? I installed JNA (i install it correctly:
"CLibrary.java (line 106) JNA mlockall successful" log record  in system.log
present on all nodes), and set vm.swappiness = 0, but this doesn't help. Any
suggest?

PS: Nodes have 12GB of memory with 6GB HeapSize
