caused by timed-out calls".
Excellent lads. Good one. +1 . And +1 on 90seconds rather than 15 minutes
(though this patch seems to have 15minutes still in spite of your comment
Dhruba).
Reminds me of another ugly one; the queue of incoming rpc requests which was
hard-coded at 100 outstanding requests * the number of handlers (So, if batch
puts, could be 2MB*100*100 of unaccounted for memory when server was working
hard).

> The HBaseRpcServer queues up rpc responses if the socket connection to the
> client is not yet ready to receive data. Calls are queued here until a 15
> minute timeout occurs. I am able to generate a full GC when I artificially
> make a client read rpc-responses very slowly. This jira is to make this 15
> minute time configurable.
