> Two things:
> * We truncate RpcServer output to 1000 characters for trace logging. Would
> be better if that value was configurable.
> * There is the chance for an ArrayIndexOutOfBounds when truncating the TRACE
> log message.
> Esteban mentioned this to me earlier, so I'm crediting him as the reporter.
