Publish Request being sent every publish interval rather than after receiving response #55

Closed pulzzedavid closed 4 years ago

pulzzedavid commented 4 years ago

I may be missing some configuration on my end. If that is the case, some guidance would be much appreciated. The issue happens as publish request is being sent from client at subscribed publish interval rather than after receiving a response. This results in server complaining about too many publish requests.

Are you using the library as a client, or the server or both? The client's behaviour is basically to throw as many publish requests at the server as there are subscriptions and to throttle if it receives an error about too many publish requests, resuming when it gets a publish response.

It should be harmless to receive the error but if it isn't let me know.

Thanks for the clarification. So, it is by design. We are using the library as a client and server. Will close and reopen this if there is an issue with the design.
