> I got a pretty reliable way of OOME'ing my region servers. Using a big payload (64MB
in my case), a default heap and default number of handlers, it's not too long that all the
MonitoredRPCHandlerImpl hold on a 64MB reference and once a compaction kicks in it kills everything.
> The issue is that even after the RPC call is done, the packet still lives in MonitoredRPCHandlerImpl.
> Will attach a screen shot of jprofiler's analysis in a moment.
> This is a blocker for 0.92.0, anyone using a high number of handlers and bigish values
will kill themselves.
