According to man page, the only way it can return EINVAL (22) is either bad filter, or bad timeout. I can't see how the filter would be bad, so I'm guessing ts must be bad. Unfortunately I forgot to ask for it, so I am going to have to ask you run it again and run p ts if that's valid, then the only thing that can be bad if the file descriptor 23.
