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.
