------------------------------------

bq. Are you actively working on this?

"no" is probably the most accurate answer :). It's on my back-burner of things to get to.

> Today, if a user happens to do something like a large multi-put, they can get through
request throttling (e.g. it is one request) but still crash a region server with a garbage
storm. We have seen regionservers hit this issue and it is silent and deadly. The RS will
report nothing more than a mysterious garbage collection and exit out.
> Ideally, we could report a large multi-* request before starting it, in case it happens
to be deadly. Knowing the client, user and how many rows are affected would be a good start
to tracking down painful users.
