Sriram Subramanian commented on KAFKA-671:
------------------------------------------
2. I am not sure if it is an issue in the first place. Depends on how long
these objects stay in the queue. If 5000 outstanding requests can be reached as
suggested by Jay above then it does seem like an issue. Let me know what you
find in your GC investigation. I agree it is ugly. Another option is to totally
remove the request object dependency from DelayedItems but that would be a
larger change.
