Subject Re: Failed to page in more queue messages

The purpose of producer flow control is to prevent the broker from running
out of memory when you try to store more messages than the JVM can hold.
So your options seem to be:

   1. Turn on PFC.  This will prevent more messages from being published
   once you hit the limits enforced by PFC.
   2. Speed up your consumers, to ensure that you don't have more messages
   than your JVM heap can hold.
   3. Increase your JVM heap.
