Subject OOM opening bloom filter
Date Sun, 11 Mar 2012 19:47:56 GMT
Using cassandra-1.0.6 one node fails to start.

This happens with (our normal) -Xmx12g setting.

How did this this bloom filter get too big?
Is the best option to keep trying with larger Xmx settings until i can
startup the node and then to do a `nodetool scrub` ?
