Ah, thanks - require_ack_response sounds like what I was missing. Some blogs are from before this was added in 0.12 so I didn't know about it.
I am still interested in forwarder failure cases - I have replied to kiyoto's comment talking about the HA docs, which still talk about some other cases that can lose messages.
In this case:
* The process dies immediately after receiving the events, but before writing them into the buffer.
Is it possible to require acknowledgement that the log event has been written to the buffer? Is that separate to what require_ack_response does?
