Subject OOM error while startup cassandra0.7.0 rc1
Date Tue, 14 Dec 2010 13:14:43 GMT
hi,
I'm using apache-cassandra-0.7.0-rc1, and use java 1.6.0_17.
The node collapse because of java.lang.OutOfMemoryError: Java heap 
space, and now it can't be restarted, becuase every time when it's 
replay the commit-logs, it will collapse by OOM error.
I have 4G memory and I tried to set the binary_memtable_throughput_in_mb 
to 128M and 64M, It's still not work.
I do not have big rows, and no row cache,use default Consistency_level...
Any ideas?
