> We had a situation where for some reason the serialization of an RPC call's
> response was throwing OOME. When this happens, the exception is not caught,
> and the call never gets a response - the client just hangs. Additionally, the
> OOME propagated all the way to the top of the IPC handler and caused the
> handler. Plus, the Handler upon exit only logged to stdout and not to the
> log4j logs.
