I keep running into this with my testing (on a windows box), Is this just a OOM for RAM?

Please first note that this is a release candidate, *not* the final release yet. All help in testing this release candidate will be greatly appreciated. Please report any problem you may encounter[3,4] and have a look at the change log[1] and the release notes[2] to see where Cassandra 1.1 differs from the previous series. Apache Cassandra 1.1.0-rc1[5] is available as usual from the cassandra website (http://cassandra.apache.org/download/) and a debian package is available using the 11x branch (see http://wiki.apache.org/cassandra/DebianPackaging). Thank you for your help in testing and have fun with it.
