No, on 0.6 copying settings for a 32GB machine to a 16GB machine would
also be a great way to OOM. The difference is that you had to set
memtable thresholds globally in the xml file in 0.6, instead of being
able to do it per-columnfamily from the cli.

Sounds like the keyspace was created on the 32GB machine, so it
guessed memtable sizes that are too large when run on the 16GB one.
Use "update column family" from the cli to cut the throughput and
operations thresholds in half, or to 1/4 to be cautious.

Looks like you don't have a big enough working set from your GC logs, there
doesn't seem to be a lot being reclaimed in the GC process. The process is
reclaiming a few hundred MB and is running every few seconds. How big are
your caches? The probable reason that it works the first couple times when
Just tried current 0.7.1 from cassandra-0.7 branch and it does the
same. OOM after three runs.
-Xm* setting is computed by cassandra-env.sh like this: -Xms8022M
-Xmx8022M -Xmn2005M
What am I doing wrong?
Thanks,
