Monitor-thread-1: Received error for message that wasn't in the cache.....

Such error happened with our production system. And after that everything goes in a deadlock for apns send thread.

There was a similar error raised in year 2014 and it was closed. But i think the issue is not resolved yet.

I'm sometimes facing same problem in our production system. send method is called but never ends nor a timeout happens

Noticed this issue also with all my threads stuck trying to send a message also, and found in the end that the problem was that we used the Executor for the APNS service to also queue the push messages.

The solution was simply not to reuse the executor for anything else.
