This is a clear indication that the hpaio backend is writing to fd 0. It's a bug in the code, either a fd declared static that's not initialized to -1, or an fd explicitely initialized to 0, or, more likely, the fd member of a struct that gets memset() after allocation and is not properly initialized to -1 afterwards. In any case, this breaks saned when run through inetd which is guaranteed to render hpaio unusable over the network with the net backend as whatever is written to fd 0 will confuse the hell out of the net protocol stack.
