Incomplete read request detected & Probable partial read occurred causing exception

[Felix.Xu]

Hi all, 

I'm looking into the codes of voldemort server, I find that if I pass too many(thousands) keys to the server(via getAll), I will get the following exception in debug mode while reading keys:

But seems it won't affects the correctness of results, does anyone have an explanation about this problem ? thanks!
