To throw a curveball, I was able to reproduce this issue where the subscription is completely frozen while using the function from the code shared above.  Interestingly, the consumer has negative permits on all four partitions, but the function isn't doing anything. So, that leads me to believe (again) that pendingAcks have maxed out the semaphore, causing the function to block while it waits for ack's from the broker. -- This is an automated message from the Apache Git Service.
