Subject Re: Nodes just dieing with OOM

Sorry about that.  We eventually found that one column family had some
large/corrupt data and causing OOM's

Luckily it was a pretty ephemeral data set and we were able to just
truncate it.  However, it was a guess based on some log messages about
reading a large number of tombstones on that column families.  I think we
should review this column family design so it doesn't generate so many
tombstones?  Could that be the cause?  What else would you recommend?

Thank you in advance.
