   The culprit here is that active acks are not properly returned as Kafka won't eat them. Therefore the monitoring for that user's queue gets out of bounds and never goes down again.
   
   I agree it's a bug and we need to be more defensive when putting the message into Kafka (i.e. checking it's size first and drop or cut the result).
   
   IIRC @rabbah did something to mitigate this?
