Push notifications every minute

I had a problem start today where I was getting push notifications on my iPhone for a customer who had not sent a message, except for 2 earlier in the day. I emailed him directly from another address and he verified that he had not sent additional messages.

I checked the site, no messages. App showed no new alerts, neither did site. push notices were happening every 20 minutes or so. I reset the app and now I am getting them every minute. One push every minute, maybe ever two.
